well, for starters, I'd suppose YC thinks favorably on the startups they've invested in. I mean, they're putting some of their money and I suspect a bunch of their time into them. Maybe I'm dense, but this seems obvious to me.

YC has posted the launched startups here: http://ycombinator.com/faq.html

So, if you were so motivated, you could contact these startups and do scoops on them, if they are so willing.
