One interesting tip I noticed from Jessica is on demos. I had originally (and probably incorrectly!) thought that the demo link on the application didn't matter, as they generally don't look at the demo during selection. When I applied, I used a custom link on the website, to redirect to the demo/mock-up when it was completed. I found out that somebody from YC visited that link, only once, when there was nothing there, so I was probably mistaken in my belief that the demo link wasn't important.
