Another tool that alll those chatty blogging librarians seem to be checking out lately is del.icio.us, a bookmarking tool that is striking for its simplicity, ability to share lists and [best of all] an ability to create your own authority control structures via a keywording system that becomes a set of hotlinked categories. I'm mostly using it presently for my "to add" list of links for librarian.net, and because I enjoy the URL del.icio.us/jessamyn.
