. Such models provide a means for connecting otherwise fragmented industries and small organizations without the resources to reach a broader audience with interested users. Social networks are providing a different way for individuals to communicate digitally. These communities of hypertexts allow for the sharing of information and ideas, an old concept placed in a digital environment.

Many people are predicting that social networking tools will replace search engines for many tasks, such as product comparison and review.

In 2011, HCL Technologies conducted research that showed that 50% of British employers had banned the use of social networking sites/services during office hours.

Basics

Social networking sites share some conventional features. Most often, individual users are encouraged to create profiles containing various information about themselves. Users can often upload pictures of themselves to their profiles, post blog entries for others to read, search for other users with similar interests, and compile and share lists of contacts. In addition, user profiles often have a section dedicated to comments from friends and other users. To protect user privacy, social networks usually have controls that allow users to choose who can view their profile, contact them, add them to their list of contacts, and so on.

In recent years, it has also become common for a wide variety of organizations to create profiles to advertise products and services.

Additional features

Some social networks have additional features, such as the ability to create groups

Lately, mobile social networking has become popular. In most mobile communities, mobile phone users can now create their own profiles, make friends, participate in chat rooms, create chat rooms, hold private conversations, share photos and videos, and share blogs by using their mobile phone. Some companies provide wireless services that allow their customers to build their own mobile community and brand it, but one of the most popular wireless services for social networking in North America is Facebook Mobile.

Emerging trends in social networking

As the increase in popularity of social networking is on a constant rise, new uses for the technology are constantly being observed.

At the forefront of emerging trends in social networking sites is the concept of "real-time web

Instead of connecting individuals based on social interest, companies are developing interactive communities that connect individuals based on shared business needs or experiences. Many provide specialized networking tools and applications that can be accessed via their websites, such as LinkedIn

Founded in December 2002 and launched in May 2003, it is mainly used for professional networking. , LinkedIn reports more than 120 million registered users in more than 200 countries and territories.

. Others companies, such as Monster.com

, have been steadily developing a more "socialized" feel to their career center sites to harness some of the power of social networking sites. These more business related sites have their own nomenclature for the most part but the most common naming conventions are "Vocational Networking Sites" or "Vocational Media Networks", with the former more closely tied to individual networking relationships based on social networking principles.

Foursquare
Foursquare (service)

 app. Recently, Yelp announced its entrance into the location-based social networking space through check-ins with their mobile app; whether or not this becomes detrimental to Foursquare or Gowalla is yet to be seen, as it is still considered a new space in the Internet technology industry.

One popular use for this new technology is social networking between businesses. Companies have found that social networking sites such as Facebook and Twitter are great ways to build their brand image. According to Jody Nimetz, author of Marketing Jive, there are five major uses for businesses and social media: to create brand awareness, as an online reputation management tool, for recruiting, to learn about new technologies and competitors, and as a lead generation
Lead generation
Lead generation, or lead gen is a marketing tool used, particularly in internet marketing, to generate consumer interest or inquiry into products or services of a business. Leads can be generated for a variety of purposes - list building, e-newsletter list acquisition or for winning customers....

 tool to intercept potential prospects. These companies are able to drive traffic to their own online sites while encouraging their consumers and clients to have discussions on how to improve or change products or services.

Social networks and science

One other use that is being discussed is the use of social networks in the science communities. Julia Porter Liebeskind et al. have published a study on how new biotechnology firms are using social networking sites to share exchanges in scientific knowledge. They state in their study that by sharing information and knowledge with one another, they are able to "increase both their learning and their flexibility in ways that would not be possible within a self-contained hierarchical organization." Social networking is allowing scientific groups to expand their knowledge base and share ideas, and without these new means of communicating their theories might become "isolated and irrelevant".

Social networks and education

Social networks are also being used by teachers and students as a communication tool. Because many students are already using a wide-range of social networking sites, teachers have begun to familiarize themselves with this trend and are now using it to their advantage. Teachers and professors are doing everything from creating chat-room forums and groups to extend classroom discussion to posting assignments, tests and quizzes, to assisting with homework outside of the classroom setting. Social networks are also being used to foster teacher-parent communication. These sites make it possible and more convenient for parents to ask questions and voice concerns without having to meet face-to-face.
The advent of social networking platforms may also be impacting the way(s) in which learners engage with technology in general. For a number of years, Prensky's (2001) dichotomy of Digital Natives and Digital Immigrants has been considered a relatively accurate representation of the ease with which people of different ages--in particular those born before and after 1980--use technology. Prensky's theory has been largely disproved not least on account of the burgeoning popularity of social networking sites and other metaphors such as White and Le Cornu's Visitors and Residents (2011) are gaining greater currency.

The use of online social networks by libraries is also an increasingly prevalent and growing tool that is being used to communicate with more potential library users, as well as extending the services provided by individual libraries.

Social networks and grassroots organizing

Social networks are being used by activists as a means of low-cost grassroots organizing. Extensive use of an array of social networking sites enabled organizers of the 2009 National Equality March
National Equality March
The National Equality March was a national political rally that occurred October 11, 2009 in Washington, D.C.. It called for equal protection for lesbian, gay, bisexual, and transgender people in all matters governed by civil law in all 50 states and the District of Columbia...

 were similarly considered to have escalated and been fuelled by this type of grassroots organization.

Social networks and employment

A final rise in social network use is being driven by college students using the services to network with professionals for internship and job opportunities. Many studies have been done on the effectiveness of networking online in a college setting, and one notable one is by Phipps Arabie and Yoram Wind published in Advances in Social Network Analysis.

 is a web hosting service that specifically hosts the user creation of web-based social networking services, alongside related applications. Such services are also known as vertical social networks due to the creation of SNSes that cater to specific user interests and niches; like larger, interest-agnostic SNSes, such niche networking services may also possess the ability to create increasingly niche groups of users. An example for this is Ning.

Business model

Few social networks currently charge money for membership. In part, this may be because social networking is a relatively new service, and the value of using them has not been firmly established in customers' minds. Companies such as MySpace

 on their site. Their business model is based upon large membership count, and charging for membership would be counterproductive. Some believe that the deeper information that the sites have on each user will allow much better targeted advertising than any other site can currently provide.

Social networks operate under an autonomous business model, in which a social network's members serve dual roles as both the suppliers and the consumers of content. This is in contrast to a traditional business model, where the suppliers and consumers are distinct agents. Revenue is typically gained in the autonomous business model via advertisements, but subscription-based revenue is possible when membership and content levels are sufficiently high.

In addition, there is a perceived privacy threat in relation to placing too much personal information in the hands of large corporations or governmental bodies, allowing a profile to be produced on an individual's behavior on which decisions, detrimental to an individual, may be taken.

Furthermore, there is an issue over the control of data—information that was altered or removed by the user may in fact be retained and/or passed to third parties. This danger was highlighted when the controversial social networking site Quechup

Privacy on social networking sites can be undermined by many factors. For example, users may disclose personal information, sites may not take adequate steps to protect user privacy, and third parties frequently use information posted on social networks for a variety of purposes.

However, because such forums are relatively easy to access, posted content can be reviewed by anyone with an interest in the users' personal information".

Data mining

Through data mining, companies are able to improve their sales and profitability. With this data, companies create customer profiles that contain customer demographics and online behavior. A recent strategy has been the purchase and production of “network analysis software”. This software is able to sort out through the influx of social networking data for any specific company. Facebook has been especially important to marketing strategists. Facebook’s controversial and new “Social Ads” program gives companies access to the millions of profiles in order to tailor their ads to a Facebook user’s own interests and hobbies. However, rather than sell actual user information, Facebook sells tracked “social actions”. That is, they track the websites a user uses outside of Facebook through a program called “Facebook Beacon”.

Notifications on websites

There has been a trend for social networking sites to send out only 'positive' notifications to users. For example sites such as Bebo, Facebook, and Myspace will not send notifications to users when they are removed from a person's friends list. Likewise, Bebo will send out a notification if a user is moved to the top of another user's friends list but no notification is sent if they are moved down the list.

This allows users to purge undesirables from their list extremely easily and often without confrontation since a user will rarely notice if one person disappears from their friends list. It also enforces the general positive atmosphere of the website without drawing attention to unpleasant happenings such as friends falling out, rejection and failed relationships.

Access to information

Many social networking services, such as Facebook, provide the user with a choice of who can view their profile. This prevents unauthorized user(s) from accessing their information. Parents who want to access their child's MySpace or Facebook account have become a big problem for teenagers who do not want their profile seen by their parents. By making their profile private, teens can select who may see their page, allowing only people added as "friends" to view their profile and preventing unwanted viewing of the profile by parents. Most teens are constantly trying to create a structural barrier between their private life and their parents.

To edit information on a certain social networking service account, the social networking sites require you to login

 purporting to be that of a former schoolfriend Matthew Firsht, with whom Raphael had fallen out in 2000. The page falsely claimed that Firsht was homosexual and that he was dishonest.

At the same time, genuine use of social networking services has been treated with suspicion on the ground of the services' misuse. In September 2008, the profile of Australian Facebook user Elmo Keep was banned by the site's administrators on the grounds that it violated the site's terms of use. Keep is one of several users of Facebook who were banned from the site on the presumption that their names aren't real, as they bear resemblance the names of characters like Sesame Street's Elmo.

, a researcher of social networks quotes a teenager in her article, Why Youth (Heart) Social Network Sites. The teenager expresses frustration towards networking sites like MySpace because it causes drama and too much emotional stress. There are not many limitations as to what individuals can post when online. Individuals are given the power to post offensive remarks or pictures that could potentially cause a great amount of emotional pain for another individual.

Interpersonal communication

Interpersonal communication has been a growing issue as more and more people have turned to social networking as a means of communication. "Benniger (1987) describes how mass media has gradually replaced interpersonal communication as a socializing force. Further, social networking sites have become popular sites for youth culture to explore themselves, relationships, and share cultural artifacts".
Many teens and social networking users may be harming their interpersonal communication by using sites such as Facebook and MySpace. Stated by Baroness Greenfield, an Oxford University Neuroscientist, "My fear is that these technologies are infantilizing the brain into the state of small children who are attracted by buzzing noises and bright lights, who have a small attention span and who live for the moment." The convenience that social network sites give users to communicate with one another can also damage their interpersonal communication. Sherry Turkle, the founder and director of the MIT Initiative on Technology and Self, stated, “Networked, we are together, but so lessened are our expectations of each other that we feel utterly alone. And there is the risk that we come to see others as objects to be accessed--and only for the parts we find useful, comforting, or amusing.” Furthermore, social network sites can create insincere friendships, Turkle also noted, “They nurture friendships on social-networking sites and then wonder if they are among friends. They become confused about companionship.”

Psychological effects of social networking

As social networking sites have risen in popularity over the past years, people have been spending an excessive amount of time on the Internet in general and social networking sites in specific. This has led researchers to debate the establishment of Internet addiction as an actual clinical disorder.
Social networking can also affect the extent to which a person feels lonely. In a Newsweek article, Johannah Cornblatt explains “Social-networking sites like Facebook and MySpace may provide people with a false sense of connection that ultimately increases loneliness in people who feel alone.” John T. Cacioppo, a neuroscientist at the University of Chicago, claims that social networking can foster feelings of sensitivity to disconnection, which can lead to loneliness. However some scholars have expressed that concerns about social networking are often exaggerated and poorly researched .

Patents

There has been rapid growth in the number of US patent applications that cover new technologies related to social networking. The number of published applications has been growing rapidly since 2003. There are now over 3500 published applications. As many as 7000 applications may be currently on file including those that haven't been published yet. Only about 400 of these applications have issued as patents, however, due largely to the multi-year backlog in examination of business method patents and the difficulty in getting these patent applications allowed.

It has been reported that social networking patents are important for the establishment of new start-up companies. It has also been reported, however, that social networking patents inhibit innovation. On June 15, 2010, the United States Patent and Trademark Office

. The patent describes a Social Networking System as
A networked computer system provides various services for assisting users in locating, and establishing contact relationships with, other users. For example, in one embodiment, users can identify other users based on their affiliations with particular schools or other organizations. The system also provides a mechanism for a user to selectively establish contact relationships or connections with other users, and to grant permissions for such other users to view personal information of the user. The system may also include features for enabling users to identify contacts of their respective contacts. In addition, the system may automatically notify users of personal information updates made by their respective contacts.

The patent has garnered attention due to its similarity to the popular social networking site Facebook.

), probation, and university officials to prosecute users of said sites. In some situations, content posted on MySpace has been used in court.

Facebook is increasingly being used by school administrations and law enforcement agencies as a source of evidence against student users. The site, the number one online destination for college students, allows users to create profile pages with personal details. These pages can be viewed by other registered users from the same school, which often include resident assistants and campus police who have signed up for the service. One UK police force has sifted pictures from Facebook and arrested some people who had been photographed in a public place holding a weapon such as a knife (having a weapon in a public place is illegal).

Government applications

Dating applications

Many social networks provide an online environment for people to communicate and exchange personal information for dating purposes. Intentions can vary from looking for a one time date, short-term relationships, and long-term relationships.

Most of these social networks, just like online dating services, require users to give out certain pieces of information. This usually includes a user's age, gender, location, interests, and perhaps a picture. Releasing very personal information is usually discouraged for safety reasons. This allows other users to search or be searched by some sort of criteria, but at the same time people can maintain a degree of anonymity similar to most online dating services. Online dating sites are similar to social networks in the sense that users create profiles to meet and communicate with others, but their activities on such sites are for the sole purpose of finding a person of interest to date. Social networks do not necessarily have to be for dating; many users simply use it for keeping in touch with friends, and colleagues.

However, an important difference between social networks and online dating services is the fact that online dating sites usually require a fee, where social networks are free.
This difference is one of the reasons the online dating industry is seeing a massive decrease in revenue due to many users opting to use social networking services instead. Many popular online dating services such as Match.com

Medical applications

Social networks are beginning to be adopted by healthcare professionals as a means to manage institutional knowledge, disseminate peer to peer knowledge and to highlight individual physicians and institutions. The advantage of using a dedicated medical social networking site is that all the members are screened against the state licensing board list of practitioners.

The role of social networks is especially of interest to pharmaceutical companies who spend approximately "32 percent of their marketing dollars" attempting to influence the opinion leaders of social networks.
