Bootstrap the social graph using iOS’s Twitter, Facebook, and address book integration, letting users find and follow users that recommend apps they like. – Andy Baio
Maybe we should expand on this social metaphor and also implement another Twitter feature:
Allow me to mute certain developers and apps based on keywords or name.
E.g. I don’t care about football. I muted everything about the WorldCup on Twitter. If I can just hide the sports category (or certain keywords) in the App Store, that’s one less useless app taking up valuable App Store space for me.
