So I’ve been using this app for a few months now, and it’s a fun social network.
You should check it out if you have an iPhone. It recently became a top-10-app after Justin Bieber & Ellen Degeneres endorsed it.
Get it from here: http://itunes.apple.com/us/app/stamped/id467924760?mt=8
UPDATE: The startup (Stamped) was recently acquired by Yahoo! It’s Marissa Mayer’s first acquisition as a CEO of Yahoo!, therefore, the app was taken down from the AppStore.
