I'm not sure that Orlowski would know what a fact was if it started stalking him. In an all too predictable hit piece on the accuracy of Wikipedia, he has a lot of fun at Jimmy Wales' expense. I guess he didn't see this piece on the overall accuracy of Wikipedia versus Britannica.
The reality is, Wikipedia's issues with accuracy has far more to do with the controversies on topical issues than it has to do with anyting else. I think I mentioned that awhile back.
