Twitter IMHO is a very poor medium for public communication. It is very difficult to discuss complex issues like gender relations or the dynamics of immigration in a sober, thoughtful, nuanced manner via streams of 140 characters. In the former in particular I actually feel there's a definite case where Twitter amplified division; the notorious "SJW vs MRA" storm advanced little if any productive discussion and merely put people in opposing camps lobbying grenades at the other side.
If this is now "mandatory" for public communication now, I feel that's a huge downgrade from public communication methods in the past.
