I developed Newspin after a few months work (mainly deciding on technologies etc.) and its received middling acceptance, even after promoting it to friends and acquaintances.
After publishing it, I decided to try out game development and published World quiz. I promoted it to no one (no one really reads this blog). Surprisingly in the couple of weeks since it was published, it has already overtaken Newspin in downloads.
Looks like I was wasting my time with app development, game development is where its at boys and girls.
