According to Microsoft, nearly two million Xbox Live users logged into Facebook through the console's new built-in social media
applications. Based on a vague estimate
provided by Microsoft, it appears that around ten percent of all Xbox Live Gold accounts used the application within its first week of availability; however, it's possible many of those users only logged in to see the new feature in action.
Microsoft also stated the addition of Last.fm
-- a music streaming service currently only available for US and UK gamers -- prompted nearly one million new profile activations. In its first week, Last.fm users streamed "more than 120 million minutes" of music to their Xbox 360 consoles. If we've learned one thing from these numbers, it's that people love to click on shiny new boxes.
