Actually, it's not that really.
I've just... gotten bored of the boards pretty much. I felt like I've done what I originally set out to do (reverse some damage, bring some renewed interest in his metagame, give pros and those who play more regularly more of a voice amongst the theorycraft, and test some stuff). I probably spend more time on these boards than what's healthy, so, you'll probably see me around a bit more, but I won't be monitoring 24/7, which is pretty much what I need to do as a mod.
Edit: Don't everyone jump up at once.
