A tweet from Marketing Manager for Microsoft Advertising Southeast Asia Geert Desager, reveals the timing of Facebook integration into Windows Live: Facebook will be added in the Windows Live activities in april, I just heard!

Windows Live Profile, the service that essentially turns Windows Live into a non-isolated social network centered around your Windows Live ID, currently pulls in a good deal of updates from third-party services Flickr, Pandora, Twitter, Yelp, and a couple more. You can also insert any RSS feed into the streams, for instance the one for your own blog, and add it to the mix. In case you don’t remember, Windows Live Profiles was part of the big social roll-out Microsoft launched in December last year, reports TechCrunch.
