Royal Pingdom did a little digging into the gender make up of several popular social networking sites, and the results just might surprise you. Think LinkedIn is mainly for men and MySpace for women? Or is it the other way around? It doesn't matter which of those notions you held, because they're both wrong.

As it turns out, the female population claim the majority of users on nearly all of the 19 social networking sites Royal Pingdom, um, pinged. Only Slashdot (about 82 percent), Reddit (65 percent), and Digg (60 percent) attract more male than female visitors. The other 16 sites have a greater than 50 percent female visitor population, according to Royal Pingdom.

If we're to take the data at face value, Bebo ranks as the most female dominated site with 66 percent of the users missing an Adam's apple (don't email us - we're fully aware that's technically incorrect). MySpace, Classmates.com, and Xanga weren't far behind, with each one made up of a 64 percent female userbase.

On average, females outnumber males on the 19 sites by a ratio of 53 percent to 47 percent, and if it hadn't been for the three news sites (Slashdot, Reddit, and Digg), that figure would be much more lopsided.

Are you surprised, or is this about what you expected? Hit the jump and sound off!
