People seeking knowledge, experience, and advice outbidding each other to sit down with people with knowledge, experience, and advice. For charity. Doesn't seem so backwards to me.
Start-up knowledge, experience and advice comes from entrepreneurs, not VCs. Read their bios, they are financial and marketing professionals. Nothing wrong with that, but they are not the kind of people who started companies from nothing and now are VCs (like PG for example).
It should be the other way around: They should be buying lunches for entrepreneurs. Scouting deals is their job after all.
