I thought that "Startup School" would be more like the "How to Start a Startup" lecture series that YC is running at Stanford.
Instead, it was just a bunch of celebrities talking about their startup experiences; a concentrated shot of survival bias. There's nothing practical to learn from the Startup School talks.
As for inspiration, I guess some people might be inspired by celebrity speeches like those, and I don't want to begrudge anyone that if that's what they got out of it, but I'm much more inspired by new products. (Especially imperfect products that make it seem easy to improve them.)
The Office Hours are the best part. Throw away the talks, let PG give a keynote, and turn the whole thing into Office Hours.
