Yeah, but the user doesn't get real attribute on the Fluther site either, beyond a screen name and a profile that (as far as I can tell) doesn't even have a field for a personal link or bio about the author.

Most sites are essentially "stealing" content from their users -- the people who submit it and retain the copyright on it (or should, if they don't) -- so this forces me to ask the overriding question here: Who really cares?
