I never thought about it before, but I have to agree that "user" is not a good description of what we are; in some software circles it also has a negative connotation as in "just a user, what does he know".
Somebody who runs Linux is a user, somebody who writes code for Linux is a contributor. Somebody who comes to Wikipedia in order to get some information is a user, somebody who writes and edits articles is a contributor.
While we probably all qualify as users in the above sense, I think we are better described as "contributors" and I would favor a change. For a smooth transition, the web server could simply redirect /wiki/user:* to /wiki/contributor:*
