Like anything, if you know how to moderate your experience and balance your time and energy, you can derive something positive getting it. Speaking from personal experience, my Twitter experience got much much better once I got diligent about adding muted words for anything political or the outrage du jour.

The problem is that not everybody does, or want to do that. Teenagers, for example, are highly influenceable (sp?) but their peers, so they get controlled by social media rather than the other way around. Same with people following celebrities/influencers. It's easy to build a collective consciousness that people compare themselves too, to their loss.
