I've been looking around for a slick 'Web 2.0' type of To-Do list for jotting down ad-hoc thoughts and ideas and stumbled across a couple useful utilities.

www.tadalist.com is a nice online To Do list from the folks at www.backpack.com . Adding a shortcut link to my browsers toolbar made this about a 90% solution for what I was looking for.

Then I found Google Notebook at http://www.google.com/notebook/ . It's an active plug-in control that let's you right click on any text and select "Note this" which adds the text to your private or public notebook.

Granted, it's not a list organizer, but it was a serendipitous little discovery that also meets about 90% of my ad-hoc note and list making needs. The ability to move notes up and down relative to each other would be a nice improvement.
