Android apps: 9 best, free social networking choices

Untappd

You've heard of Twitter and Facebook, where you post the mundane details of daily life online. You've seen Foursquare, which lets you share your location with others. But you may not have been introduced to one of the latest social networking crazes, Untappd, a mobile-based service for beer drinkers to share and discuss their various brews of choice. Find new beers and breweries, connect with other likeminded drinkers and earn tons of creative badges for your troubles. You'll never drink alone again. Cheers. (Note: Untappd is a browser-based Web app, and it works on iOS, BlackBerry and other mobile platforms, as well.)
