I understand wanting to put forwards a more gender-balanced mix. To do it in such a ridiculously ham-fisted way shows no knowledge of either the subreddits they're promoting or the Reddit community as a whole.
2XC [doesn't want to be a default](http://www.reddit.com/r/TwoXChromosomes/comments/24z7fe/poll...), and it's place in the defaults will likely be corrosive to the community it already has. And half of the population aren't welcome there anyway (unless one toes a very specific line).
Plus Creepy, NoSleep and Philosophy? Seriously? I think Reddit's admin are utterly disconnected from the Reddit gen pop.
