Idea: quote tracker / favlet

Often when i'm reading blogs or other information sites i read a paragraph or soundbite that really sticks with me and/or defines the content and/or concepts. Wouldn't it be nice if there was a favlet or greasemonkey+ajax script that could let you highlight and then save a quote to a remote server (either a central repository or your own configurable receiver)?

You could use something like this to display a updating list of quotes, as a meta-data extension to Del.icio.us or to help you organise your bookmarks, perhaps to manage citations on your own website, build up an index of searchable quotes... lots of ideas i guess.

I suppose to be fair, Del.icio.us lets you do this if you select some text and hit the "tag" button... but it isn't specifically a quote that could be used later (unless you tagged it "quote" perhaps?) as the highlighted text is pasted into the "notes" field .

An idea to play around with i think, it could be some fun to experiment with "BJAX" concepts.
