The problem is that there are a few, very active, and very stubborn power users that know how to use Wikipedia and navigate it's internal processes. They posses incredible power to make all their favorite articles conform to their own vision.
Every time I go to edit something, it immediately gets reverted by a major contributor, who cites some rule or process that is described on a page I've never seen before and don't know how to find.
Wikipedia should just stop with the charade. They should stop saying it's open to everyone. It's more like an open source project that only accepts edits from it's developers.
Wikipedia's biggest problem is the brain drain. They're no longer relying on the wisdom of the masses. In this case, if you get a prankster who puts in the time to get some Wikipedia cred, then they can put in pretty much any hoax they want.
