I'm toying with starting an occasional blog for posting odd bits of coding related stuff (mainly C++, probably).

Are there any platforms which can be recommended as providing exceptionally good support (e.g syntax highlighting) for posting snippets of code ? (Or any to avoid because posting mono-spaced font blocks of text is a pain).

Outcome: I accepted Josh K's answer because what I actually ended up doing was realizing I was more interested in articles than a blog style, getting back into LaTeX (after almost 20 years away from it), using the "listings" package for code, and pushing the HTML/PDF results to my ISP's static-hosting pages. (HTML generated using tex4ht). Kudos to the answers mentioning Wordpress, Tumblr and Jekyll; I spent some time looking into all of them.
