I see value and artistry in trolling. The trick is being a smart audience. If the audience gets riled up by trolls, it's no good for the trolls and for the community. However, trolls have the power to instigate valuable discussion and debate, almost in a sacrificial manner. In a way no one else can.
Throughout history, many of the greatest progress has been brought about by contrarians and troublemakers. It's no different for social networks. Alas, Steemit is not mature enough yet to handle provocation.
We discussed trolling over here yesterday. Maybe you'll find it worth reading.
