"Now that there are some 10,000 applications available at the App Store, it makes it much harder for new apps to be discovered, some developers say. Brandon Bogle, an engineer and a co-founder of the Blimp Pilots — an ad hoc group of iPhone-app creators, who are otherwise employed as game developers — said its hit app Koi Pond, which sold 600,000 copies, was simply in the right place at the right time. "We were lucky enough to get in on day one, when people could find us. There are so many good apps for the iPhone, the problem is that now it's so hard for them to rise to the surface." Bogle said he and his partners had no desire to quit their day jobs."
