Facebook is 63.88% Women

According to this, Facebook is more than 63% Women. This really doesn't surprise me, but that makes me wonder what percentage of people on MySpace or LinkedIn are male or female (I have a hunch more men will be on LinkedIn, more women will be on MySpace). I, personally, liked Facebook about 99% more when I first started using it before it opened its API than I do now. Now, it is just annoying.
