Yes, I noticed a lot of bump ups for facebook pages, though they aren't unique and only serve as doorway pages.
In my opinion, social shares should never be in the SERPS as they don't help the end user and it only makes the users click twice to go to the destination, than a single click.
But this stuff makes things clear. Get ready to be flooded with Google+ pages in SERPS.
