The Berkman Center for Internet and Society is exploring cyberspace. Some of its philosophical convictions are:

Technology can transform education.
The collective wisdom of academics is valuable.
Access to education should be easy.
Credit should be given where credit is due.
The best software is developed by its own community.

To facilitate these visions they provide the social software H2O. The collaborative, mostly academic playlists "...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."

These playlists facilitate the following:

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.

You can browse/search these tags/playlists for the most influential, recent or the most viewed or create your own and join in.
