Microsoft’s statistics says that the first week of Facebook availability resulted in almost two million people using the app on Xbox Live. This means that about 10 percent of users have pounced on the chance to use the app.

Furthermore, in the first 24 hours alone, users have created half a million Last.fm accounts and streamed as much as 120 million minutes of music among them up to date.

Unfortunately, while Microsoft said that the Xbox Live community was buzzing with tweets from nearly every market featuring Xbox Live network, they didn’t reveal any numbers.
