fwiw - As a lead engineer I tried to influence meeting formats as being "review only". The idea is to distribute ideas as wiki or markdown prior and review/comment prior to meeting. It failed spectacularly. I believe the demands of multi-tasking (meeetings, chat, meetings+chat+work at the same time) have caused a lot of people to not have the will power to sit and read. Reading is considered "not-productive" when you can just go to a call and ask the person to explain.

In short, its really hard to change bad habits.
