Separately, upthread is a post where somebody suggested the 18 star, rounded couner flag is twitter emoji. It is (a twitter emoji). Link to the emoji is also upthread.
Thanks! I'll backtrack later. Twitter emoji makes sense as a source for the icon. (The video, after all, was on Twitter.)
What I'm trying to determine is what was the message (if any) in making the superfluous, redundant addition of it -- following the appropriate (50-star) flag?
