I was not there but as an older male, who doesn't drink, I am constantly reminded of how young and alcohol obsessed "entrepreneurs" seem to be. David Rusenko (Weebly) was still in college when he and his buds started. So to me it seems like college boys dominate. And the kinds of technically oriented women that would be interested in Startup School aren't as interested in hanging around with a bunch of drunk college kids where there are not that many women.
Id be curious if the gap was smaller watching the webcasts?
