"Non-English Editions" -- if you take off your propaganda goggles, you find out that Wikipedia is full of misinformation (English or not). It is true of any popular web site. Nothing special.
Yeap. It's mostly corporate editors, crazy people, and egotistical know-nothing amateurs who cobble together Wikipedia with semi-inaccurate information. Oh and try to correct them with first-hand knowledge? Rejected!
For most topics, English Wikipedia is more accurate than any other article you are likely to find on Google without looking too hard.
> It is true of any popular web site
Including this one.
Wouldn't a crowdsourced medium not tend to reflect the post-truth society in which it is embedded?
