Some people are morning people and some people are creatures of the night. My mind is much sharper in the mornings. Most of my co-workers are better at night.
Over the years, I've tried emacs several times. Then I tried VIM, and it clicked with me. I think some people's brains click with VIM and others click with Emacs.
I used Tracks for to quite a while. I liked that you can host it on your own machine. I have a problem with some hosted site for my todo's. I too am looking for something that does hierarchies.
I used Anonymous for a while, but then I switched to Consolas. I'm not sure if Anonymous is free or not. One site wants to charge you for it, and another has it for free(no, not the Pirate Bay!).
