I do keep a running log of ideas in org-mode, but it's by no means comprehensive (I can only really use it at home). I keep most things in a notebook, but typing is so much faster I can't help it. I have a few files for various topics; I usually just create a new org heading for each timestamp and write a few paragraphs. Presumably I could tag each timestamp if there was something important, but I rely on search more than tagging. Each heading looks like (* Mon Sep 17 17:51:24 EDT 2012), newest up top. I open up the .org file, M-S-Enter, C-u M-! date, C-n and start writing. Not going to win any organization awards, but that's not what it's about.

It seems useful, just as useful as writing (except the not-always-with-me part). Getting an idea out on a screen or on paper is usually helpful, if only so I can forget it and clear my mind.
