Having some sort of capture device, like pen and paper, is a good way to free up your attention for the speaker.
As you're listening, you'll be struck by some thought or another, some idea to follow up on, some insight. If you can write this down quickly and cheaply, you don't have to occupy your mind with remembering YOUR idea. Then you can listen more freely to THEIR ideas.
I discovered the value of using a trusted external system to store stuff like this, instead of only my own mind, when I began playing with David Allen's ideas in his book Getting Things Done.
