A brief observation on the nature of a web-geek conference: There's never, ever a line for the women's room.
Some would choose to look at this as ire-raising evidence of patriarchal oppression in the tech industry. In fact, in this crowd, a very small protest to that effect may break out at any moment in front of the restrooms.
I prefer to look at it as a lucky convenience. But I'm a bright-side kinda gal. Plus, I'm totally a lapdog of the patriarchy. Or, that's what I read about myself in a liberal blog one time.
