This semester I will publish selected lectures for my Sociable Media course. Podcasting is great but it is also a bit petrifying to hear my Germano-British accent. Listening to it, I had to confront my occasional generalization but it's a rich pesentation that,  I think, will be worth your while. You can subscribe to this podcast series of lectures. If you listen to it in Itunes or Jukebox you'll miss the presentation slides). Alternatively, you can download the video of the first lecture here (34 MB, 45 mins, m4B file opens in Quicktime or VLC).
