Yeah, so I don't see a lot of people using the Channel or Communities part of WhatApps. I am in a few, but they are all muted and/or archived. I never read those messages. 

I see a lot of people in large groups, but they never read those messages, even when they ring their notifications all the time. My mother used to delete dozens of group notifications when unlocking the phone to search for the ones from her friends. It's really bad.
