I'm now using ikiwiki with darcs in my own server and saying goodbye to wordpress.com. I tried to install wordpress before trying ikiwiki, but it was just eating all the memory of the server. And after using ikiwiki, I thanked wordpress for misbehaving, because ikiwiki is so much better. It's everything I wanted, but I didn't knew I wanted until I tried it. Just like sup.
My homepage, which used to be my page on the Debian wiki is not being hosted here too, and it's great to have it so nicely integrated with the blog.
I also thought about trying gitit, since it's written in Haskell, but it doesn't seem to support blog easily. And now I'm so happy with ikiwiki that I doubt I'll change.
