I think the only thing that is really missing which hampers social in the current browser is lack of push notifications. What would be ideal is if I could close Facebook but still authorize push notifications when something happens, this can be done in something like Growl but it doesn't seem like a major use case, remote push notifications.
I recently saw that push notifications had been proposed in the HTML5 spec then later removed, not sure why. Although I still think that you have to have a tab open on the site to receive them.
