which dvcs do you use?

git and darcs here.

git for github mainly. but darcs is more simple (on how to manage on my mind)

I completely agree on the bug thing. That's fucking awesome. As for the wiki, I don't see a reason to put this into the VCS. If you mean for documentation, that's better done with literal programming and simple text docs in a doc/ prefix. Hell, maybe even using a documentation generator.
