I consider myself an avid Yelper. It is a great way to find new restaurants, and recommend those that are your favorites. This past summer, I really put Yelp to the test when I drove cross-country, and it turned out to be an irreplaceable tool on this trip! It helped me find places like Snooze (www.snoozeeatery.com), an awesome breakfast eatery in Denver, CO. As great as Yelp is for finding some delicious new places to chow down, the “stars” rating system is all relative, and to somebody like myself who doesn’t know who wrote the review…those stars are even more useless.
Stamped is taking a new approach. They are getting rid of ratings, and relying solely on whether you liked the place or not. If you thought the place was worth a visit, then stamp it. If not, then leave it alone. It’s as simple as that. I can imagine that if there is some Facebook integration, then this could really grow into being a great way to see which of your friends like particular restaurants.
