H20 Playlists

I'm excited about H20 Playlists:

H2O playlists are more than just a cool, sleek technology -- they represent a new way of thinking about education online. An H2O Playlist is a series of links to books, articles, and other materials that collectively explore an idea or set the stage for a course, discussion, or current event.

H2O Playlists make it easy to:

transform traditional syllabi into interactive, global learning tools

share the reading lists of world-renowned scholars, organizations, and cultural leaders

let interested people subscribe to playlist updates and stay current on their fields

promote an exchange of ideas and expertise among professors, students, and researchers

communicate and aggregate knowledge -- online and offline.

See also their philosophy. They take basic tagging and kick it up a notch; notice -- here's a sample playlist -- how you can leave comments on others' lists, view derivative playlists, rate playlists' influence, and view playlists with the same tags. I love it. Even though I created my own playlist but it wouldn't let me publish it ("An unknown error has occurred."). Oh well, it's still in beta.

UPDATE: It works for me now, and my first playlist is up.
