App-store listing is a whole other animal. I don't care to go through all that just to share my app. I also don't care to resolve every technical issue others experience.
Every time I've thought about generating revenue by selling my apps, two thoughts come to mind: my code is not professional-grade, and the field is so competitive than within months a professional will likely create a better app so why pollute the web with something subpar.
The hacker on the street corner isn't distributing his "secret sauce" because it wouldn't meet standards, but it works well for him, and it was cheap/free.
