Twittering in My Lecture

Mark Tucker was in the 5:00 lecture I gave at the BYU conference yesterday and he was twittering while there, which I thought was really neat.

I'm wondering what others think of twittering during a lecture? Either from the attendee perspective or the speaker perspective.

Here is Mark's initial tweet.

And one more. There were several more during the lecture, but I won't link to them all.

Here are most of the tweets from the conference.
