As title. It is not intuitive at all.

I know theres a big app there somewhere - costing USD 75 - that could replace my social groups app - but it is not easy to find.

Also: The free ones, the most downloaded ones and the featured ones are on the frontpage - but to find the really big apps in this jungle is difficult. So my feedback is that you should improve the markedplace so that we - the customers - can find the good stuff easy.
