Which is why I'm sure there's going to be something new coming along one of these days: something where users are in control of what they post (e.g. not a wiki unless the user who did post does accept himself others' edits).
Collaborating to answer questions is fine. But modifying and closing questions artificially (due to very serious moderators issues) isn't acceptable either.
So I'm waiting for the next big thing and I'm sure it shall come.
