Those specific anecdotes were also really useful because they let the audience go home and do more research on their own. If someone says "a company did this thing and it worked/didn't" that's useful. But if they give you actual companies who do a great/terrible job on different things, then you can dig up a lot more information after the fact and keep learning.

I agree with everyone who said it was a great event. Thanks to Paul, Jessica and everyone at YC for putting it together.
