I really love Blosxom: Blosxom, the Blog software you read right now. Clean, simple, easily configurable. I just added some new flavours, including a home-made text one, with a calendar plugin and a category tree list. Quick and simple.
I put my blog file under RCS control too. A simple makefile enable me to create .txt file with a single command. That's allow me to edit my files as I which, create a logging section, and move things around as I which. Well, this can break the permanent link however... I have to find another way around this.
Also, I'm looking for a wiki formatter... There is some available, but all seems to use an already install wiki formatter, which I want to avoid (especially that I want to customize it). Maybe I can create my own?
