If a word falls on the web and nobody sees, does it exist?

Would I need to know more about computers to answer this? (I don't know much about them)

No, this is irrelevant because the point is that the word is generated randomly and that despite how it is created, no-one has seen it.

Are we talking about the meaning of words independent of human input? Why is a stone called a stone?

A stone is called a stone, although I am no linguistics professor, as an arbitrary designation to distinguish it from other objects. It hasn't got anything to do with its intrinsic properties

It is relevant if my answer to "what is a word on the web?" - which is linked to your question? - is that a word on the web is binary code stored in a server somewhere (or something like that, i.e. my answer to your original question will involve first looking for the referent of the word, 'word'). Although having said that I can see why it might be irrelevant.

Also I wonder if you contradict yourself when you say "the point is that the word is generated randomly" and then say "despite how it is created". I am only saying this because I have to wait for a little bit. Is this really you Fendogg? (always pictured that with one "g" btw). I would like to say that things don't need to be perceived to exist.
