I've recently been considering the addition of a Wiki to my site in order to manage the non weblog-oriented content. It's kind of a pain to manage multiple pages with similar structure, and a Wiki makes that simple, with the addition of remotely-editable content (well, I have that now, via SSH, but I'd prefer something even simpler). I'll need a Wiki engine that allows for HTML in the content, as I'm not a Wiki purist, and I want some control over the presentation on my pages.

I'm on the hunt, so watch out for it.
