Thinking of the tweets you corral Elle, I wonder why that guy was saying to us no tweeting during the show. First of all, I doubt anyone is going to spend an entire night tweeting. Secondly, the light from the tweeting phones wouldn't be any worse than the light used when phones are in camera mode. There
is light from the screen, even when you aren't using flash.
The contemporaneous tweets make great advertising for future shows.
If you see those tweets and you know LB is going to come to your area in a few days, they could spur you to go out and get tickets.
