Whiteboards are absolutely indispensable for communicating ideas quickly in a small group of people. It's effectively just a bigger (and easier to erase) version of grabbing a scrap of paper to scribble something down when explaining or describing something to someone else.
I'm honestly more surprised that this isn't a universally known concept on HN. Scribbling on scraps of paper is something most people in western countries have done since pre-school.
