WiFi in the Lecture Hall
WiFi in the lecture hall (in the New York Times) is the latest environment to add "back-channelling", which is members of the audience or class using instant messaging or group chat to discuss the lecture. SXSW a couple years ago was my first experience with WiFi enabled conference sessions and back-channelling, which was a little distracting, but at the same time provides another dimension to information input. Insta-fact checking would be very nice in work meetings.
