This talk summarizes a big chunk of what people submit to HN.
The arguments about bootstrapped vs funded, lifestyle vs selling out, lean vs not, MVP vs GDP, internet celebrity worship - all covered pretty well in an hour.
I don't see why AdWords couldn't work if you built the right experiment. For example, a simple email-capturing landing page with a price tag doesn't touch on it as much as personally talking to people and finding 30 who will (not would, as Jason emphasizes) pay at that price. You can learn a lot from just talking to folks, and an AdWords campaign could help you get in touch with the right people.
Initially I was also thinking Jason writes better than he speaks. But as edanm pointed out, the talk gets remarkably good very quickly. It's one of the best I've seen recently.
How to filter advice from others. Brilliant advice, but don't take it as the absolute truth.
