Is putting 2XC on default perhaps a strategic move in response to the rise of tumblr? Tumblr has a pretty large number of very-active posters across a broad range of feminism/lgbt/racism/etc blogs. Basically if you can come up with something that can be discriminated against, there is probably an active tumblr blog about it. Assuming it doesn't alienate too many other users, pulling in that very-active userbase might be a lucrative move for Reddit/Conde Nast.
