Not in any one single way :-) I think you might want to look at http://www.toodledo.com/ http://www.toodledo.com/ - it is actually quite powerful (aka "complicated") but the amount of complexity is user configurable. So if you don't care for a certain category, you can just tell the system to ignore it. The main advantage of something "online" is that it is easy to attach supplementary information to a to-do item - a file, a message-ID... I use a hybrid of post-it notes, online calendar, paper notebook, toodledo, and e-mail. GTD it isn't - but it works. [Edit - toodledo also allows you to assign tasks to other users. It is not quite implemented in the way I would like, but their deveoper is very user-friendly and they are always working on it, so I am optimistic.]
