NerdFitness, anyone?

Inspired by the likes of Staci, I'm tempted to join NerdFitness. Apparently they've just recently rolled out NerdFitness Academy, which, for $59 or $99 is a lifetime subscription to their workout academy/support forums/whatever. I'm tempted because I like the idea of, well, nerdy fitness and accountability, but hesitant because it's kind of hard to tell exactly what this 'Academy' entails, and they're also pretty keen on a paleo diet while I'm more a balanced w/moderate grains type of person.

Anyway, has anyone here tried it out? Pros/cons?
