The article does come across as though she's acting very much the 'self-involved woman pirate whore' she's trying to avoid, but it's her site, her prerogative.

Casting that aside for a moment, biology happens. I'm a guy, married and have been hit on in the past (my best defence was to stop working out and put a few pounds on, hasn't been a problem since then although it may have introduced new problems which I'm now working on).

It's natural for men and women to flirt, to hit on each other in an attempt to achieve evolution's goal. It's what we're all wired for. However, having said that as long as boundaries are made clear it shouldn't be a problem.

I'd also like to say that I have both been 'that guy' and been hit on by 'that woman'. In both cases there are worse things in the world to worry about. In the case of 'that woman' I made a pretty good friend and business associate, in the case of being 'that guy', you chalk it up and move on, or in my case make friends with someone who you wouldn't have perhaps spoken to if you weren't initially attracted to.

I'd also second the context. A woman being hit on in SF is nothing like being hit in Cairo, Delhi or even Paris.
