Will you be my Advisor?
cperciva: What is your startup?  If you're doing something which I find technically interesting, I'd be happy to advise; if you're writing software for printing bingo cards, it would be a waste of both your time and mine.(No offense intended to patio11 -- bingo cards was just the first example which came to mind of a successful startup which doesn't have the sort of technical challenges which I find interesting.)
