Wikipedia may be getting more mature, but I think barrier to entry is also cause for lack of outsider edits. Also, being a wikipedian isn't like being a professor. You don't get much outsider respect. Due to their policies, you also see "forks" or more specialist wiki such as comixpedia, or libregamewiki(A wiki that I actually found) for subjects like webcomics or open source video games that keeps getting deleted. Gwern, who is a veteran editor, got so tired of the wikipolitics(Even though he's really good at wikilawyering to protect his contribution when needed), so he started http://gwern.net http://gwern.net He benefit from the reputation and traffic that would otherwise goes to wikipedia.
