Y Combinator cofounder Paul Graham vs. “one cranky attendee”

Why might this this summer's batch of incubator Y Combinator's startups bore you, as they did "one cranky attendee" who told Silicon Alley Insider so? Because you're not as talented at spotting early stage startups as Y Combinator cofounder Paul Graham, says Paul Graham in a comment on the SAI post:

Statistically it's almost certain there will be startups in this batch that go on to be highly regarded. It's a rare skill to be able to judge startups at 10 weeks. I know because I've spent the last 3 years trying to acquire it. Most people who attempt to perform this feat are, like the cranky attendee (and 200 TechCrunch trolls), doomed by not even realizing they lack this skill. But the fact is, most people who'd seen Google at 10 weeks would have thought they were lame too.
