I have to agree with the sentiments about Facebook. Interesting for a while, but the novelty has worn off (altho' I do still enjoy the odd game of Scrabulous).
Besides that, I pretty much only scan statuses. It's a way of staying in touch with lots of people - getting a quick snapshot of how they are - rather than using it as a platform to interact with them (altho I use email occasionally). It will be interesting to see if FB Chat changes that.
Excellent presentation. I'm glad you re-published it, as I hadn't gone that far back in Dave's archive. The other point - particularly with respect to an educational situation - is that, if you have too much text up on your slide, your audience tends to concentrate on writing down what's on the screen, instead of listening to - and engaging with - what you've got to say.
