I'm really much better at absorbing information through reading rather than listening. This becomes truer as the event becomes larger. It becomes staggeringly true if the event is taking place in a wirelessly equipped conference hall.
"Let's make this Constructive" Update: In comments, Megan suggests knitting through long meetings. Keeping your hands busy with rote work focuses the mind. I've known others who employed that strategy and it always seemed to work for them. But I'm pathetically heteronormative and am not willing to start knitting my way through press conferences. I generally try to take notes by hand, as that helps, and I can't refresh Tapped during it. Any other ideas?
