Like the concept, but find the navigation somewhat problematic.

My somewhat naive assumption is that if I'm on this site, I'm looking for the answer to a specific question. I dunno, like, what are the advantages of C# vs. Objective C. But all I can really to in terms of navigation is use the clunky search interface (would probably be better off just typing the search terms into Google) or drilling down into categories that are so high-level they're not likely to be particularly helpful.

Curious -- what's your ultimate goal with the site? I noticed the AdSense, so is that the angle?
