If we're all on a Brian Wood lovefest, I'd suggest picking up Local from Oni Press. It's written by Wood with art by Ryan Kelly, and in the same format as Demo -- 12 issues, 12 individual stories, all tied together by a common theme. I'm actually enjoying Local more than Demo.
Here's some more recommendations:
If you like Kane, but you like superheroes, also, check out:
Jack Staff (Image) -- superheroes by Paul Grist.
Exterminators (Vertigo) -- this has Preacher vibe all over it (not that they're even remotely similar, but the vibe is similar)
I'll try to come back with more, but you can always check out my reviews for more suggestions.
