using zotero to manage citations

I am probably the last person in the world to find out about zotero, but I have downloaded it and find it extremely cool. It's an extension for firefox, and you can use it to keep citation information and other extremely useful things.......like adding notes, taking a picture of the page, even adding tags to citations. This is a list of databases/sites that work with zotero, and they don't have all possible citation styles yet. Here's also a nice youtube tutorial from zoteron which explains it pretty well.
