Sadly, there’s no “am I dominating the conversation?” multiplier. That’s the sort of thing I wild have lived to have in a hackerspace’s monthly meeting.
I am always fascinated that in US conversations Robert's rules of Order are assumed common knowledge (and in a way I envy that there's somewhat consensus that in a debate you use Robert's rules instead of reinventing the wheel each time people meet) but as not having ever been to the US it took some research to figure out what these rules actually are and if there are alternatives or how things governed by Robert's Rules are handled elsewhere (reinventing the wheel it seems)
