I very much like Dresden Codak as a comic, it fills the hole in my heart left by A Lesson is Learned but the Damage is Irreversible, and I really like that sort of comic book science fantasy but it's a classic example of what the XKCD writer dismissed as "shouting science in the same way you'd shout Alakazam!", I'm not sure I'd pitch it for it's treatment of the singularity.
