I've been trying to learn enough Objective-C and Cocoa to be able to communicate at some level with a future co-founder (or even a contractor if I can find one within my bootstrap budget). It's slow going, though, and a first-mover just launched—the hardest question now seems to be just how much of the territory I want to be familiar with before I take the next step.

But I think you have a good benchmark there: Do I know it well enough yet to have a good idea of when I'm being bullshitted?
