This seems like a great way to do things. Currently I have topical folders, and it isn't very optimized. I have things that I want to read (a few people's blogs, tech, security news, etc), and things that I might like to read (e.g. book reviews), and things that might be funny or a pleasant distraction (e.g. cat pictures) all mixed in together.

Moving to a priority model where folders are listed in order of general importance to me, sounds like a real improvement -- the ability to nuke lower priority folders without concern.

Thanks for the idea.
