One of the more interesting concepts, I think, is the many ideas for how to incorporate microblogging (think Twitter) into your content management system. Drupal Voices via Lullabot interviews Rob Loach and briefly talks to him about his Distributed Micro-Blogging proposal which received a grant from the Knight Foundation. The audio recording is only two mintues long but there is enough there to get you started thinking how microblogging may eventually play a role in the larger world of content management.
