Has there ever been anything released on this topic?
I happen to be a 60-yr old developer with his first app about to come out of public beta and hit the AppStore. I believe iOS app developers are pretty rare in my geographical area and I suspect my age adds addiitonal rarity. I'd be curious to see some data on this but all I've seen is the financial summary of how well the AppStore is doing.
Is there any way to tease out a little more detail? Age distribution, geographic distribution, anything?
