News.YC isn't trying to compete with Digg and Reddit. Really; the last thing I need is to have to manage servers with that kind of traffic. The goal here is just to be the watercooler of the startup world. That is a quite small world, tens of thousands at most. I'd much rather this site had really good comments than huge volumes of traffic.
No doubt. What's interesting though is that the level of discourse has been really high, and apparently we're good folks to have visiting other sites (according to this article).
Have you updated your traffic graphic recently? It'll be interesting to see if we can maintain good participation after Startup School and this batch of YC applications.
I used to read reddit, never commented/submitted anything, however. Reddit, these days, is full of things I have absolutely no interest in. n.yc is perfectly aligned with my interests. I hope it doesn't degenerate into another reddit.
