Google’s brand new +1 button has been added to Android Market app listings so that you and your friends can help each other find the best apps around. Well, we’re still trying to figure out exactly how it’ll work, but if it’s anything like the search results +1 button, you should see results every time your friends and contacts give it the go. Should be a good way to show your friends if you think an app is legit. Be sure to start using it!
