I’m talking above my pay grade, but I guess observers who are genuinely curious about why their observation was rejected or their notes were ignored, should assume that the identifier has too many notifications to read, so they should DM (Direct Message) the identifier. Which might be explained in the identifier’s profile.
Like @spiphany said:
I realize this is asking a lot of observers, but like anything in life, you get out of it what you put into it. If you want to get more learning out of your observation, then you’ll probably have to put more effort into communicating with busy identifiers who have vast numbers of unread notifications.
