Assuming the site exits beta in a few months, what kind of logo should it have?.
Alternately, I could go for a hexahedron, tetrahedron and icosahedron (d6, d4 and d20) arranged like the boxes in gamedev.stackexchange.com's logo.
I'm going to say a d6 being touched by a glowing wand. Yeah, the wand is fantasy-centric, but probably we can admit that so is the hobby.
Honestly, I would really rather the stack of different types of polyhedral dice, but this logo has to scale down to a 16x16 favicon. We have very little real estate to work with when you take that into consideration.
