Via Sullivan, some reasons to forget what you heard about guys and the web:

When you look at internet usage, it turns out women in Western countries use the internet 17 percent more every month than their male counterparts. Women are more likely to be using the mobile phones they own, they spend more time talking on them, they spend more time using location-based services. But they also spend more time sending text messages. Women are the fastest growing and largest users on Skype, and that's mostly younger women. Women are the fastest category and biggest users on every social networking site with the exception of LinkedIn. Women are the vast majority owners of all internet enabled devices—readers, healthcare devices, GPS—that whole bundle of technology is mostly owned by women.
