I Twitter-follow Steve Stewart-Williams, and strongly recommend him as a followee. (Provided only that you agree with him (and me) that evolution is real and that doubting it is foolish, in which case he might make you angry.)
Or, to put the more general point the other way, if all you get from your Twitter feed is political bile and general nastiness, you’re not doing it right.
