Comment Phone with To Do App (Score 1) 300
I suppose it depends on your field and the nature of the conference, but I think that most of the time you can distill some take home key points and some "things to look up" in just a few short lines. When I attend a conference or lecture, I open my To Do app on my smartphone and just jot a few short items: IE - Newton talk 8/11 - Force=massxaccl. wiki this later or []look through old thruster data - were the forces equal AND opposite?
Adding things to my to do list forces me to attend to them at some point and also forces me to be concise and selective about what I choose to write down - resulting in a good signal to noise ratio.
