This is exactly the technique that the more efficient managers I know use: make people commit to exactly what they want to say and discuss at the meeting beforehand.

Me as well. What I don't see is people saying "I want to have great/efficient meetings, but I just don't know how."

Maybe this can make the job slightly easier for people who already run good meetings, but I'm skeptical it's going to convert anyone.
