Correcting you: I got the impression pg wants to know exactly who will be your customer and what problem you're solving. He asked that again and again. (saying what problem you're solving is not marketing talk)
Ah, perhaps I should have phrased that better. What I meant to say was:
For pg's office hours, you should strip away all the buzz words and describe your business (customer, market, etc) in words someone outside of this industry would understand.
Basically, I got the feeling he was trying to pare away buzz words.
