At any rate, anything in-app is siloed data and will trap people into a client, but it allows you to write all sorts of nasty stuff you don't want anyone else knowing about, so I see the upside. If you're doing it client-side, why bother even using the pics from the profiles? You could change my profile pic to anything.
