Windows Live Pulls a Teenage Werewolf, Turns Into Social Network Overnight

Home.Live.com
As of last night, Microsoft’s Live.com is now a full blown social network in addition to a search engine.
In conjunction, Windows Live Photos and Windows Live People have both been launched.
Users are automatically ‘friends’ with all of their contacts on Windows Live Messenger (#1 messaging service worldwide with 268 million users vs Yahoo’s 116m).
Similar to FriendFeed, Live pulls in your content from around the web including blog posts, Pandora, Twitter, Flickr, Yelp and RSS.
A Facebook-like activity stream announces every change to your profile and every photo you upload or review you write.
Yahoo had been talking about building this out around their email platform a year ago.
