Bill O'Reilly may think he's taking on DailyKos with his seemingly daily attacks on the liberal mega-site. But if you look at the numbers, he's doing them a huge favor. According to Jotter, a Kos blogger who has made an art form of digesting and analyzing the site's user data, in the last seven days, the site has gained 1,959 new registered members--483 in just the last day. Compare that to the 6,168 new members that joined the DailyKos community in the three months from April-June, and you've got a whopping boost in DailyKos's popularity. It has a total of 131,738 registered members in all, making it the equivalent of a small city.

According to Alexa, traffic to DailyKos has also surged in the past two weeks. (Visits to BillOreilly.com are flat, by comparison). See below:
