Im sure that you have a lot in common with people that you meet in rehab, but by ALL MEANS make sure you associate with "normal" people.
Sometimes, hanging out with all people in recovery is setting yourself up, all the drama, all the slips, etc.
I find that I have enough to deal with just taking care of my OWN recovery.
Not that it cant be good to remember where you came from, just keep your eye on the prize.
