Of course you thought wikipedia was a gag site! What a moron. Ironically, Chase now has a Wikipedia entry. (Currently under consideration for deletion.)
Wikipedia has some detractors: http://www.wikipedia-watch.org/
I'm not a purist when it comes to the "right" of anonymity of the internet. In general, I think everyone should have to stand by what they say and do on the internet - as they should in "real life." However, there are times when doing that can get you killed or put in jail.. even here.. Perhaps Wikipedia should work to get the users trust enough to privately manage identities. I believe that Wikipedia has already placed restrictions such that only registered users can create new pages.
