Found this article via my friend Adventuresaurus Girl, about dating in San Francisco, and confirmation that I am not crazy or fugly.
Having lived in or spent extensive time in other US geographies, it's absolutely true that men do not make the cold approach here. The ones that do are usually new and haven't been 'brainwashed' by the bros/nerds around them.
That said, most of us SF transplants chose this city for more reasons than just the gender ratio. I chose it because it draws intelligent, physically active, and liberal people. So if I am surrounded by like-minded men, there is a possibility I may meet him here.... the only question remains how. :)
