Can Trump do a shout out on Twitter for people to switch to Parler?
Sure. Many people on twitter whom I follow are urging people to do it now. Some suggest we have a twitter free Friday every week to facilitate the transition. The recent permanent removal of Carpe Donktum has sparked an uptick in leaving twitter.
Doesn't have to.
The entire world will know within 48 hours.
Twitter stock values will plunge so fast there will be no way to sell positions.
