Geek to the Nth power

Wow. See if you can count the exponential geek power in this:

At Pax (1), the Penny Arcade (2) Expo , they hold a concert featuring two game-related artists, Mini Bosses (3) and MC Frontalot (4). At one point, the latter challenged the former to an onstage head-to-head competition on pre-relased (5) Guitar Hero 2 (6).

Yes, that's geek to the sixth power.
