None of these will happen.<p>- Push notifications the question is asked up front, good enough. Later on you can ask them to turn it on for benefits, that means notifications have to be worth it. This is the only way to control spammy abusers of notifications.<p>- I agree 30% is high for physical goods but you'll have to raise prices on iOS. We are sharecroppers on a platform that we didn't build, they built it, it is the new normal. It's either feudal or sharecropping but that is what platforms can do and will. Smart competitors would lower their take (Play!, Amazon, Windows, BB) but they won't because it is greed and that is the new norm, just following the Apple script. Until there is competition here on the fees/take noone will budge.<p>- Profile photos are available in plenty of places, gravatar, facebook, g+, etc. Maybe there is a startup that wants to aggregate all these and you can easily call that service. Doesn't need to be in the OS level. It would be great if profile photos had some common standard but everyone is building walled gardens and not sharing.
