Ps. While that counts only people that have a linkedIn profile, I would remind you Facebook has more women that guys, so I would assume that women are very familiar with social networks, and not afraid of them.
I'd think women would be way over represented in that, at least, when I was at Google, it was the recruiters and HR people flocking to LinkedIn, not the engineers. FWIW, I was on four teams at Google. I was the only woman on all of them except for Orkut, which was about half women.
As a personal anecdote, the m/f ratio in a company (one of the biggest ISPs in my country) a friend worked was supposed to be 67-33, according to LinkedIn. When I told him that, he said that certainly it wasn't the case. He worked in their HQs, along with as much as 90% of their employees, and one of the first things that made an impression on him was that women were so much more than men. By the way, there are profiles of 183 employees of that company in LinkedIn, with the error margin not sufficient to explain the discrepancy.
