Hate to be the bearer of bad news but you're outdated on this point. Researchers & politicians of repute use Twitter to voice their opinion and share stuff with the public.
I didn't say these platforms are never used. In this context I don't regard the public as an entity where you have a meaningful engagement on a topic. An individual yes, but the public as a whole is broadcast to.
Hate to break it to you, trump likely never read your tweets...
