I haven't linked to CNN.com as a Resource site for quite a while, mainly because I think they're quite biased. This impression has been reaffirmed by their dismissal of blogging as a significant journalistic development as well as their continuous anti-war/pro-terror spin.
The first story is pretty well-known by now. CNN prominently ran an AP wire article about how few people maintain weblogs, but that number (around 7.3 million) is more than ten times higher than the number of people who watch CNN (450 thousand). Yeah, that's insignificant.
Most interesting to me, however, is instance after instance of biased reporting. It may not be obvious in every piece, but over time CNN makes its political stance clear by the stories it chooses to cover. Ace of Spades has an excellent example up of how the top story on CNN all this morning was an anti-war protest in Washington DC attended by a mere 60 people. He later notes that pro-life marches in the capital that drew upwards of 50,000 were not covered by CNN at all. (Here's the coverage by Fox.)
