That's why you're more likely to attract HN users than the sites which are trying to compete directly :)

HN used to have a lot more in-depth "AskHNs" before Quora came along. Quora never tried to compete with HN, but rather it solved the problem that people were using HN for.

Plenty of people who use HN want curated startup content and intelligent discussion and will go wherever that's found.

In any-case more high-quality startup communities are good for everyone (YC, VCs, founders, etc.) so I don't think that competition is likely to be a significant issue for anyone.
