The rapidly evolving sphere of technologies and applications that facilitate collaboration is startling. One example which we hadn't heard of is H2O Playlists, a fascinating project to allow experts (or "filters") to create playlists of books, articles, sites and other material and thus "set the stage for a course, discussion, or current event". And this from the site's About page:
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.
