> The HN audience (mostly young, nerdy white men) have always been one of the worst demographics for social networking products...

Wow, that's a very racist/sexist statement and you don't even leave a hint about why you think it's true. Worse, it reads like you expect it to be obvious. What about a person's gender or skin makes them "a bad demographic for social networking"?

Edit: Also presumptuous of you about the HN crowd. Where would you even get those statistics? HN doesn't collect that data.
