I tried a few years ago, but killed my account when I realized that having all of the posts literally designed for maximum outrage show up in my feed was causing stress that I just didn't need in my life.
There's one statistician on Twitter that I check periodically. They often post links to interesting papers. Unfortunately they often post snarky remarks as well. Recently they called Nate Silver naive in a fairly condescendingly way. There was no explanation about why the Nate Silver tweet they were responding to was naive, just an assertion and condescension. The level of casual disrespect among Twitter users is awful.
