Please do share some of these "new" ideas. The only ones I've seen are Groupon clones and each seems to get worse than the next. (Not to mention SMB's hate Groupon after using it.)
Off the top of my head: Ness, TinyReviews, FourSquare, Stampt, Perkville, Giftly, MotionLoft, Savored, Gobble, Farmigo, Rewardli, Prism Skylabs, Zaarly, Local Hero, Red Beacon, SeatMe, ZeroCater.
