Back in the days when blogging was the social media choice of the chattering classes there was plenty of creativity going on. Then people seemed to dumb down on mass. I think this has meant that we have handed the discussion of "worthy" matters back to those with traditional power. In the brief period when we embraced the internet as a way of educating and changing the world the traditionally powerless were powerful for a while. We actually made good things happen and bad things not happen. I do not see that happening on Facebook. But it could if people aimed higher again.
