Actually, if done right, this could be a very good ad-on to Gmail and reduce the amount of BS created by "social networks".
Point in hand: the current way I use Facebook is only through Gmail. I login to my mail and see if I have received an (important) message from Facebook. If not I don't go to FB, if yes, I do go to FB.
I hate having to login to many systems, so I avoid going to facebook unless there is something there explicitly for me. I see all the rest of the content as garbage.
Basically, I use facebook as a static-web-page-mass-email system.
Now, if G brings social networks to Gmail, but in an intelligent and controllable way, then I am all for it. I might do more, just because I don't have to re-login to Facebook and Twitter and see all the garbage others do. I want to make my own garbage in peace ;)
