Facebook, it seems, has finally overtaken Google's Blogger to become the top social media site on the Web. According to new data from comScore, the social networking giant had 221 million unique users at the end of December 2008, compared to 225.5 million users for Blogger. Assuming that Blogger's traffic remained flat and Facebook's upward trend continued in January, Facebook should have overtaken Blogger by now.

In the category of engagement, both Facebook and News Corp.'s MySpace have shown gains over the past year. MySpace actually has a firm lead in that category, growing 15% in January to 266.3 minutes per user, per month-a 31% increase over last January. Facebook, meanwhile, showed an increase of just 4% since December and year-over-year growth of 3% to 176.6 minutes. That means the average user spends about 90 minutes more on MySpace than they do on Facebook. TechCrunch's Jason Kincaid explains that January's spike is probably due to a combination of the recent launch of MySpace Music, and the struggling economy, which leads people to spend more time at home.

Kincaid also notes that MySpace still leads Facebook in page views per user. The News Corp. site averaged 579 page views per user in January, a 10% increase from December, while Facebook averaged 337 page views per user, a slight 3% month-over-month increase.
