First of all, Twitter and LinkedIn are going to be a seamless part of Windows Phone along with Facebook and Windows Live, which means that users may get bombarded by notifications once they are logged in to all social networks simultaneously. That is why the ability to filter your notification feeds has been added meaning that users will be able to view either all notifications at one place, or just the ones from a network of their choice.
The second major improvement regarding social network integration in Windows Phone Mango is that the notification experience has been taken to a whole different level. Users will be notified upon events such as their mentioning in a Tweet or whenever there is some activity on their Facebook wall, for example.
