Earlier this year, Microsoft unveiled a comprehensive activity stream architecture for Windows Live. This activity stream (sometimes called “Messenger social updates”) flows throughout popular PC, web and mobile phone services such as Messenger, Outlook, MSN and the new Windows Phone 7. This means activities sent to this newsfeed have the potential of surfacing where some of the most meaningful social interactions are taking place on a monthly basis:
- There are more than 500 million active Windows Live IDs
- Messenger has more than 298 million active accounts worldwide
- Hotmail has more than 359 million active accounts worldwide
- Windows Live Messenger climbed to #2 worldwide in total daily active users connecting to Facebook
- the Messenger iPhone client has been installed millions of times
- Windows Live activities flow to the “People Hub” of the new Windows Phone 7
As a site owner, allowing users to share activities from your site to the Windows Live activity stream represents a new opportunity in social distribution. It lets you connect your application to potentially hundreds of millions of Windows Live users and their devices. It’s hard to understate the value of tapping into a pipeline to such an enormous number of people.
