"my real suggestion is that Y Combinator should invest more"
He's missing the whole point right here.
Y-Combinator is like Twitter. Venture capitalists are like bloggers.
With Y-Combinator, like twitter, people just didn't understand how so much value could come out of so little. At first, typing to someone in 140 characters is hopeless. Then you try it, and you realize how much can come out of so little--you become resourceful and cut out the fat you don't need.
Hate to liken them to twitter, but hey, everyone's doing it... (best reasoning ever)
