I don't use an iPhone, but on Android it sorts contacts based on how frequently you call them. That seems like the only logical way, at least for the dialer app. In Gmail for example, I don't need to sort contacts, because my use case is sending an email to a specific person --- I type their name and they pop up (I think Apple mail does this too). Please don't interpret this as snark or sarcasm, I'm just looking for a use case -- when is this useful? which situations does this improve upon? ------ EDIT: i totally missed the "social feed" aspect. Seems like the best aspect of this is showing social updates from people in your actually contact list -- like a high priority follower list. I probably follow thousands of people across social media but i really only care about a few dozen people. A combined feed of their updates is actually valuable to me.
