2. As someone who's not from SV, everything in that area gets lumped into "SF" for me. My apologies if this is considered obtuse.
3. Isn't this kind of part of the point of seeking investment? Aren't you saying, "I can't do this all on my own, I need some help with the finances, and will cut you in if you'll hook me up"? Somehow I don't see that as the same thing as "please pay me a pittance". As I stated in another reply, if the founder could live on a pittance, the chances are he'd save up a little bit at his cushy corporate job and enter conservation mode with that, rather than seeking external funding.
4. I haven't looked for a few years, but I was not aware that YC offered an additional $100k in financial instruments. This is somewhat better, but I'm not sure how those instruments work in this specific case so I can't make a complete evaluation. As far as follow-on investments go, these all have their own separate terms, yes? Unless YC is officially brokering all of these, how can being a YC company prevent you from getting suckered by YC copycats?
