Very good, been reading it for ages and highly recommended.
i love these comics... i particularly like the kilobyte one!
Yes been on my list for a while, girlfriend likes it too.
The death one about the death of the creator of D&D is priceless.

Probably my favourite XKCD :) Along with Dilbert and the Joy of Tech.
XKCD is starting to over take even my love of Dilbert!
Ohhh and the guy built and actual ball pool in his fromt room. What can beat that!!
