If you've spent any time gaming on Android, you probably remember OpenFeint. Nearly every major game integrated it in some way, usually allowing players to log in with a single username, collect achievements, and post scores to a global leaderboard. It was handy for what it did, but if you didn't care about competing, it felt a lot like obnoxious spamware. Unsurprisingly, it closed down in December of last year. Today, however, it's being sort of reborn as OpenKit, a project headed by one of the co-founders of the original service.
