Yesterday, the gang at Slate launched a new website, Double X, described as, "mostly by women but not just for women." The online magazine-sized version of Slate's incredibly popular XX Blog is already full of thoughtful and entertaining content: discussions on the state of modern feminism (or, conversely, why modern feminism can suck it), astonishment at the mystery that is "Jon and Kate Plus Eight" star Kate Gosselin's hair, and a fantastic essay by blogger Marie Myung-Ok Lee, who writes about the decisions and difficulties associated with using marijuana to medicate her autistic son. (I'll have some more to say on that later.) It's enough to make any other newly-launched website feel a little intimidated. More importantly, it's enough to keep you reading, thinking, and laughing for a good, long, time. Welcome, Double X!
