Mine's self-hosted. My personal internet endeavors are small-scale enough that I have been able to host my own domain services on my own machines for years. I ALMOST tried to write my own system for running my blog, but in the end I went with Wordpress, which seems to allow enough homebrew (no pun intended[1]) HTML and the like in my posts to do what I want. Plus, I have just enough of a grasp of PHP that I think I can set up my own custom extensions when the time comes and I feel the need.
