The Todo.txt Command Line Interface (CLI)

This looks quite slick (though it's sort of ironic that a non-GUI, text-based tool does not have a simple text-based description; I skipped most of the video).
I wrote my own CLI note taker (aliased to '@'), have a Ruby app that interacts with Todoist.com via the CLI; have CLI tools for setting reminders to ping me via Twitter; am starting on one to manage issues on GitHub repos via the CLI.
They're all fairly simple and designed around the principle of WFJ: Works for James. And I've always believed that I'm not alone in hacking out little helper tools like this.
(Incidentally, I'd just recently started learning emacs and hadn't heard of org-mode before your comment. Thanks - seems useful so far.)
EDIT: This is really the type of stuff I'd love to see more on news.ycombinator.com -- tools to make me more efficient.

And combined with GeekTool, I've got a list on my desktop at all times. http://projects.tynsoe.org/en/geektool/
so all this does is ... color-code task priorities - meh
Plus how long would it take you to accidentally type "echo blah > todo.txt" instead of "echo blah >> todo.txt". I'm thinking a few days for me :)
This is all academic of course, everyone should be using org-mode for todo lists. What do you mean you don't have Emacs running all the time?? ;)

it's simple: if you have any shell aliases, you are a hypocrite if you complain about this being just that.
