Adele Reaches Milestone in 'X-Factor'-Heavy U.K. Chart Week

While most of the Social 50 chart is rather sleepy this week -- there are only four re-entries and zero debuts -- the most exciting news comes from the woman who just debuted at No. 1 the Billboard 200 albums chart: Adele. She vaults 37-23 on the Social list with a 32% increase in new week-over-week Facebook fans and a 57% jump in Twitter followers.

The Social 50 ranks the most active artists on the world's leading social networking sites -- YouTube, Vevo, Facebook, Twitter, MySpace and iLike -- using a formula blending weekly additions of friends/fans/followers along with weekly artist page views and weekly song plays. (Vevo makes its debut as a contributor to the Social 50's tabulation this week.)

Akon slips one to No. 7, Shakira rises three to No. 8 and Taylor Swift slides 13-9. Rounding out the top 10 is the non-moving Linkin Park at No. 10.
