They're forming tagteams? I wonder if any other partnerships will emerge.

I also said Microsoft Skype to distinguish it from FB- didn't know that FB and MS have been collaborating. But on second thought, it really is going to be Microsoft Skype from here on out. Or rather, 2012 Microsoft Skype Home Edition 7 with .NET Windows Live integration.

It should also be noted that Facebook chat works within Windows Live Messenger 2011 and you receive Facebook notifications (or birthday updates) from within Hotmail. So Microsoft has been working with Facebook for some time now.

Wait a second: what does Twitter even have to do with video conferencing?
