It is sad that the moral seems to be: "build many small apps and don't mess with custom UI because you'll need to keep the price low".
It's business, not art
Why wouldn't you want to diversify your risk and make interfaces that users find familiar if you're trying to sell to as many people as possible?
It's kind of scary to think that app development has, in fact, become a commodity and that larger businesses are simply gobbling up up-starts and dismantling products. As someone who loves to make things, that's kind of a scary thought.
This is great. I think there is a very important point being made here, which is the question of whether or not Apple's current "app store" set up is overall beneficial for the app ecosystem.
I am also noticing a shift from emphasizing good product/design towards "app store optimization".
What happened to all those great mobile ad platforms that were the big craze at mobile conferences? One would (maybe naively) think that there would be better ways to market & find apps by now :)
