Among this week's mix of articles, there's a very sobering story called Surviving the App Store about one successful (and admittedly lucky) indie game dev's climb to the top of the Apple App store—how it paid well, but not as well as you may think. The typical indie developer can expect to make $5,000 at best. You have to take Apple's toll and other taxes into account. It's not all bad, and there's plenty of tips in the article about how to get the best possible gains for yourself through getting your app featured and more. It's an essential read.
