If you ever want to separate out the "doers" from the "talkers", try cancelling a huge weekly meeting that's been in place forever and that everyone "knows" is crucial. I did that two years ago. The "doers" were relieved because it left them with more time to do thing. The "talkers" were in a tizzy and immediately started figuring out what kind of new meetings to schedule. What they came up with were meetings that were much more useful, and I believe that cancelling the old meetings were an essential step for that.
