I seem to be looking for a strange mix between wiki and blog - a WikiBlog. I want it to be easy for people to jump to today's entry, and I want it to be easy for them to look at all the pages I'd edited for the day. I want to make it easy for people to subscribe to pages they're interested in and to have the day's work delivered to them in their mailbox at, say, midnight the next day.
Bah. Forget them. ;) I want something that can organize information for myself. For the most part, planner mode and emacs-wiki suffice. But I also want to be able to make this information usable to other people, and that means formatting it nicely.
