Well my CDJ is singulartoast, and I've got most if the above 'usual' things in there, but I also use it to post things for my characters - icon expression tables, and I'm working my way through bios and soundtrack for each. Just random things that I think help me develop my character's personalities and likes/habits.
Plus I use it to post any brainstorming I do for thread/plot ideas, but they're all locked to the journal.
