Jerry,
I don't know if it qualifies as GTD....but my approach to meetings is only to schedule them when it is necessary...and only when there is an advance agenda.
When I run a meeting, I try to keep the agenda moving. So, if speakers get off on a tangent or are repeating things that have already been said...I tend to summarize and move to the next item. At the end of each meeting, I review action items and assignments. If there are no action items, I don't bother to schedule a followup meeting.
I'm known for taking lots of notes but I rarely share them. I want others to get in the habit of taking their own notes. Taking notes keeps me engaged. If someone relies on my notes, they could easily check-out and not pay attention and contribute.
We also use daily standup meetings (we call them scrums) for quick status updates on projects to avoid the traditional sit down meeting which tend to go on too long.
Our culture is to also share info via email so that we can avoid lots of meetings.
My greatest frustration is when I must attend a meeting that is run by an individual who doesn't know how to make them productive.
