The good folks over at Techcrunch found that Wikipedia was given special treatment for its wikia and other wikis.
I think this goes directly against what they said earlier regarding all outbound links will have the nofollow tag. For those that do not really know what the fuss is about, wikipedia put the nofollow tags on in hopes it will cut down on article spam.
Here is the snippet that Techrcunch was looking at.
