It always bothered me whenever Groupon and Living Social were referred to as "social commerce" companies. Buying coupons is not a social activity (i.e. by sharing you're basically announcing to the world that you are a cheapskate who won't pay full price). On the other hand, with their recent iOS upgrade, Foursquare may be in position to become the first true "(offline) social commerce" company. I've used their "Explore" function in the past and had a good experience - There's something comforting about the fact that I'm going to a bar or restaurant that's been "vetted" by one of my friends.
