Explore a wide world of brews and beer-drinkers
Untappd is a social network for avid beer-drinkers. You can find your favorite brews, rate them, add friends, and give them a virtual cheers to whatever they’re drinking.
Locations can be attached to beers you’re checking into, so you can share your brews out to Foursquare too. That location-awareness even lets you find bars that might have a particular favorite beverage in stock. Over time, Untappd figures out your drinking habits and can suggest new beers that might be up your alley.
The user interface on Untappd is really sharp, and I find it's a great way to add a new twist on the same ol' getting drunk rigamarole.
