Wikipedia seems to get out in front of the news on a lot of stories. They knew about Palin pretty much first, and they broke this story, and when Rumsfeld resigned, I got a great tip from a source close to the Pentagon, but Wikipedia already had it.
But the more controversial aspect revolves around the constant editing and gaming of Wikipedia entries. Palin's, in particular, became kind of a cause wikipedienne.
But hers was not the only one. And I would argue that there's sort of an early period where wolves circle the campfire of any crticial entry.
