The Android marketplace is getting big -- there is no questioning that. Part of what makes mobile app stores successful is quantity -- but it's definitely not everything. In fact, when the ratio of bad apps outweighs that of good, it can actually hurt.
Instead of making tools that encourage people to create crappy meow apps, give developers better tools to build great apps. Compared to iPhone, and even Windows Phone 7, it's a nightmare making applications that look and feel half decent -- developers struggle making good stuff on Android.
Not only that, developers in countries like Canada and Australia are on the verge of boycotting Android due to the fact that you can't charge for your apps once you've made them. If devs can't make money, they aren't going waste their time. What do you think of Google's new tool?
