Is Wikipedia still a wiki?
Well, for the the most popular articles, especially for politics-related article, the answer is “no, it’s not”. Not even for administrators.
It’s not a wikicracy, it’s a trollocracy.
When an admin tries to edit the article on Sarah Palin, one gets this warning:
Administrators Attention!
Do not edit this page without consensus on the talk page or be prepared to be blocked.
It says that you should get a consensus on the talk page first, an impossible task, because of all the lobbyists (paid or not, who knows), who bring you in the wonderful realm of circular logic and of non-sensical arguments. They throw random policies without explaining how and why and begin arguing about the meaning of each word. The talkpage is a madhouse frequented only by trolls.
A sane person, when surrounded by such individuals, would lose his/her interest and try to find people more rational, on other subjects.
