Who’s on top in social networking?
Here’s the data from ComScore as of the end of November:

Top Social Media Sites (ranked by unique worldwide visitors November, 2008; ComScore)
1. Blogger (222 million)
2. Facebook (200 million)
3. MySpace (126 million)
4. WordPress (114 million)

Now I don’t know what the overlap would be (i.e. unique members) but it looks to me like there are about 1/2 a billion social networkers out there.
