With an ambitious strategy for expansion, Facebook is getting into MySpace's face.Facebook, the Internet's second-largest social network, was originally popular on college campuses, but over the past year it has opened its dorm-room doors to all and seen its membership rolls explode at triple-digit growth rates.Some of the new features, demonstrated by software developers at a Facebook event in San Francisco on Thursday, will allow members to recommend and listen to music, insert Amazon book reviews onto their pages, play games and join charity drives -- without leaving the site.The Facebook invitation is expected to result in a proliferation of new tools and activities for Facebook's 23 million active users, who have largely been limited to making online connections, sharing photos and planning events.
