[accrual]

Several comments about personal note taking systems. Here's mine. :)

    function note { mg +-1 "/home/user/notes/$(date "+%Y-%m-%d").txt"; }

"mg" is "Micro Emacs clone" and "+-1" opens the file at the bottom for appending, but of course it works equally fine with your choice of $EDITOR.

I like this setup because it's plaintext (or markdown if you prefer), easily sorts on filename, and easily greppable. I have a couple years of notes saved this way and it's fun to explore old notes.
