which online encyclopedia?

[falsereality]

i came across an article that was sayin how theres been a lot of competition with online encyclobedias. i was completing oblivious to this, ive always just gone to wiki any time i wanted an article on something specific, and i never really even wondered if theres other options in encyclopedias. and i dont fully trust wiki since its put together by anyone who wants to post an article, i know theres administrators and all, but its nothing like printed encyclopedia thats almost completely dependable.

So the question im getting at is - Which [free] online encyclopedia do you most depend on/trust? And how do they comb out false info?
