Users could see lists of other users who have furled a URL, and read their comments (if made public) to find users who share interests, supporting folksonomy

. A dynamic recommendation list was automatically generated for each user based on the sites already saved by him or her and other users with similar interests. Lists of the most popular items for today, this week, and this month (and by topic) were also available. It was possible to subscribe to a user's archive (or to a set of topics in a user's archive) to get daily email notifications whenever new items were filed.

Limitations

Images which were embedded links were not archived with the HTML page. For example, when an HTML page was archived via Furl, the location of the JPG from the HTML content was saved, thus pulling up that image when the user's personal copy was loaded; however, if that image no longer exists on the original server, it was lost and will not display with the user's archived copy. So, a Furled site with many pictures could end up being just text.

The search result displayed items from the entire Furl archive, or only from a user's own archive, but the sequence of these results was automatically ordered. There was no option to display results by date order, by popularity order, or in any other particular sequence. It was not obvious how the results are ordered.

The popularity of Furl exposed users to performance problems which began in the latter half of 2006 and persisted into 2007.

Updates

New features were released in early 2007, including an updated user-interface. On January 30, 2008, Furl unveiled an updated user interface.
Furl shut down its services on April 17, 2009.
