Most of the tweets and posts made by JW's on social media (especially after an assembly) can be classified as "Virtue Signaling"

They all make the same superficial and Cliche' public expressions, in order to appear virtuous in the eyes of their peers.
#BestAssemblyEver...# BestLIfeEver.... translate to "Look at how theocratic I am everyone !".
They probably don't even remember what was said at the assembly nor do they think it was any better than the last one. They are more interested in how they appear to the others in the group and how virtuous they get to feel when they make these proclamations.
