Toodledo your to-do's

I've been trying out a free online program for managing to-do lists called Toodledo. It lets me create my lists and put them in folders, code them with tags, goals, due dates, etc. I can access it from any computer, and I can also export the list to excel or print out a mini booklet to bring with me. I've only been using it for a week and can't tell yet if this will be the answer for my scribbles on scraps of paper and edges of books.
