Actually girls in NYC are attracted to success and most women here are very impressed by "I started my own company in NYC". Although this is where your ability to "massage" the truth comes into play.
If you massage the truth about your company, it's inconceivable that I would sleep with you, let alone take you seriously.
In taking you seriously, I am interested in your business (working with you, connecting you with people who might benefit your company), so lying to me will actually hurt you because you'll portray your company inaccurately.
Honestly, I don't think it's very many. There was a poll a few days ago and I think the male to female ratio was was something like 9:1.
And I'm pretty sure I can sometimes (with very high confidence) identify women who don't read Hacker News.
