This is very interesting, but the topics covered make it seem like YC is only focused on advising companies how to raise more money.
Maybe it seems that way because this talks about all the stuff that's common to all the startups, and the things to do with the product are usually more startup-specific than those to do with investors.
I'm the last person to give you writing advice, but maybe some examples would help.
I'd also say that even the fundraising stuff isn't just about raising money. Having a smart angel investor give you feedback on your startup isn't just about raising money; it's also about building a product, a team, and a company.
