We've thought about this, Android is definitely a more accessible option for many potential developers. However, currently iOS still has a majority share of mobile revenue and seems to be more in vogue with people who are looking to build games/apps. Down the road we hope to be platform agnostic as there is a huge opportunity in Android, however at this stage we would like to maintain a sharp focus.
I'll be straight, tho i think what you people are doing is awesome, i still think you are just riding the hype.
Android game development would bring so much more people since it could be done from Apple, Windows, Linux, etc! First time programmers prolly won't end up selling games since its their first try and its going to prolly suck, the good thing is that they will learn how to think while coding.
