Todoist

So this is a slightly boring post, but if you are slightly anal and love to keep track of to-do lists like me, this site is awesome:
http://todoist.com

It's an interactive (think gmail) website that will keep track of all of your todo items. You can nest items inside of other items, have due dates, priorities, labels, it can SMS you if something is due, and more! And it's built with a lot of shortcuts that make it really fast to use if you take a few minutes to learn them. And because it's on the web it's available almost everywhere. It looks nice and clean too--no ads or clutter, just usefulness. And it understands a lot of text the way you do: if something is due a week from Thursday, you can type "next thurs" into the due date blank. Awesome! There's even little video tutorials ("screencasts") to help you get started.

Best thing to come out of denmark in quite a while, as far as I can tell.
