I feel like this mechanism for collecting questions is not very good - I am receiving an email for every comment on this thread after commenting once, which was 50 emails in the space of 10 minutes... I was able to unsubscribe from all notifications, but not unsubscribe for this particular post because it doesn't show me as subscribed when I go into the context ellipsis menu for this post - my only option is to subscribe? It's also very clunky vs using the chat feed in YouTube.
