Yeah; I remember having to do an update once, because an old API was considered to have something like "unsafe security features"-or something... but my app never actually touched any of those features. Then over time; I received two more emails claiming that I should update the apps and I couldn't be bothered... I can't remember how many downloads I was getting, but it wasn't much at all, so it just didn't seem worth it.
I'm hoping the other store fronts are a bit more indie-game-developer-friendly.
