My problem with wikipedia is not that anyone can edit it, it’s that I don’t know who edited it (most of the time). My proposed solution - Accapedia. Same basic concept except: the editors are identified by more than an IP address, you must have a .edu email address or be invited to be a part of the site (invite is probably better), you have a profile that demonstrates why you are an authority in this area, and you include a reputation system. Sort of Wikipedia with a social aspect, and less anonymity.
Thoughts?
