Firstly, what do you mean, they can't find the good apps? There are already tens (hundreds?) of thousands of apps, and people seem to do OK with the store rankings, ratings, and with word of mouth.

Secondly, I'm curious where you found a magic oracle to tell you how to eliminate all the bad apps from the store, but keep all the good ones. I don't think that "(eq language objective-c)" is that oracle.
