I have a TODO list and notes about Linux and Bash and similar stuff, which act like personal knowledge bases. :p I also keep very detailed work notes for whatever task I'm doing that I'd be lost without. But they're all just TXT files I have aliased so I can open them in an editor with a shortcut command. I don't understand the need to get fancier than TXT.
