I need to be able to put ideas into multiple classes: "implemented", "rawdog", "RSS", "silly" and so on, and generate indexes split by classes. It would probably make sense to split this page so that each idea (or each month of ideas) gets its own page; it would also make sense to look at merging this stuff with the UKC quotes scripts, since they're both essentially just doing simple weblog stuff.
Implemented as ajournal.
