CMSes
I have a habit of liking or wanting solutions that are halfway in-between two established ways of doing something. Any programmatic web site is basically a factory for similarly-shaped objects, but CMSes are even more rigid and cookie-cutter (since otherwise the additional structure it provides wouldn't work well), and often don't even use the extra power that putting things in a big database could give you.
Right now I'm typing these first entries into a text editor to try to get the size and flavor down, but I want to write a custom CMS just for this very soon. I'm thinking the Atom feed will collect entries by the day or something, to avoid flooding people – or it'll just have many entries.
