At first, I would often display the widget on screen during the lecture, and discuss any tweets as they came through. But after a while the tweets slowed down. There were only half a dozen or so eager students using the service, and the novelty of this tool soon died.
Maybe I was just too early with this trial. Are there enough users of Twitter amongst our undergraduate student population yet?
