Social computing will play a big role in Microsoft's upcoming collaboration platform.
The Newsfeed displays information from other users or things that you follow, such as people, documents, sites, and tags. It displays 20 items, sorted in reverse chronological order, just like your favorite social network (go on, pick one). The Newsfeed is just one of several feeds available via My Site. The Everyone feed, for instance, shows the last 20 posts or replies across all users, not just the people you follow. And the Activities feed shows all activity associated with a particular user. Other users can see your Activities feed while browsing your profile or About Me page.
