It's seems to be carved out of news section from Wikipedia frontpage, like Wikia was carved out of Wikipedia trivia sections. It's again Jimmy who launches a private company and suddenly Wikipedia changes the rules to forbid trivia section to boot his for profit offspring. Conflict of interest it's called.
It of course not easy to point to older events with a still working link, when 1) Wikipedia deletes it's own history, 2) Wikipedia and trivia are such common words it's hard to find, 3) even news sites change so much.
Random slashdot comments aren't a source and don't back up what you portrayed as a conscious effort by Jimmy Wales to forbid trivia sections for his own personal gain. Maybe it's just possible that the editors themselves decided those sections weren't appropriate?
> Wikipedia deletes it's own history
Only for copyright violations and offensive vandalism. It never has for anything else, but of course you won't back this claim up either and will make up more excuses.
Conspiracy theorists just dig themselves further and further into a hole, to the point where everything else is also a conspiracy against them getting their "truth" out.
