As some of you already noticed, there have been some changes to Windows Live in regards to Twitter: the service was available as one of some 75 social networks that you could bring into your Windows Live feed, but it has apparently gone missing recently.  Now, according to an email distributed to Windows Live users who had added the Twitter feed, there’s a bit more of an explanation:

Dear Windows Live Customer,

Thank you for connecting your social networks and other services with Windows Live. We are contacting you because you have added your Twitter feed to Windows Live and we want to notify you of an upcoming change. 

Beginning June 30, 2010 your tweets will no longer be automatically imported from Twitter and shared out to your Windows Live Messenger friends due to policy changes made by Twitter. We are working hard with Twitter to make this service available again and apologize for any inconvenience this may cause you.

We remain focused on making Hotmail, Messenger, and your PC with Windows great companions to social networks and other services. This change has no impact on your ability to connect Windows Live with our other 75+ other social networks and other service partners, which include Facebook, LinkedIn, MySpace, Flickr, and more.

Sincerely,
The Windows Live Team

Whether or not Twitter was concerned with allowing many millions of Windows Live users access to their feed, or exactly what happened, we’re not sure.  Hopefully Microsoft and Twitter get it resolved soon.

(and don’t forget to follow us on Twitter – aaaaack, just couldn’t resist!)
