I think that's the kind of lesson one should learn fairly quickly if you talk to experienced entrepreneurs. I was at a panel fairly recently where literally every single panel member (including a VC guy) mentioned you should never make the mistake of thinking that talks, no matter how advanced, with a VC mean a deal is forthcoming, and that you should always be continuing to look for other options until the pen hits the paper. You don't really need something like YC for that lesson; just talk to experienced entrepreneurs or other VCs (assuming you have some contacts with either camp).
