I have been using www.tadalist.com for my To Do lists. Over the weekend I started using www.RememberTheMilk.com and I really like it.
- I can assign priorities and due dates independently.
- I can have as many lists as I want so I can separate work, personal, LMSPodcast, and others as needed.
- I can add tags that indicate where the work will take place, such as www, computer, phone, and home.
It looks like a very easy system for applying the "Getting Things Done" (GTD) system of time/project management. And it even has a special interface for access from my iPhone, that is quick to load and lets me access my lists from anywhere.
Bye, bye, TaDaList. Hello, RememberTheMilk.
