But in being productive, which would you prefer to see as a response t a post - 6 x 
, or 6 additional posts to “Yep, I agree”, “Great idea” & so on?
I get notifications all the time to show that someone has left a reaction to one of my posts, which may have been from 6 months before! That has only come to me, but if they’d then actually posted to say “I like it”, everybody who had followed that thread would have been advised of an update that they would have to read.
To me, a simple emoji reaction is a much better idea.
