The kind of activism undertaken when you "do something" about a problem by tweeting or posting links to
Facebook, without any intent of ever actually doing something. Nothing more than a nonsense feelgood gesture so that
one can say they "did something about" whatever
trendy cause they're pretending to care about. Usually only lasts a week or two before the cause is completely forgotten (i.e. it stops being cool to forward/retweet on the subject).
