Hello Kees, thanks for your response. Sorry if my post came across as blaming the individuals of facebook, or any other social media. That was not really what was intended. I believe the operators and purveyors of profit seeking social media are more naive than anything else. My intention was more to bring attention to the blindness we seem to have as a society, to the damage being done to ourselves by profit seeking in the wrong place. We seem to have to find these things out by trial and error, unfortunately at huge human cost. Believe it or not, I am all for technology, and firmly believe the world could be a much better place with the right technological systems in place https://medium.com/@eric.bott/a-priceless-evaluation-of-value-a162c7245f90. A further article that might be needed to put that in context is https://medium.com/@eric.bott/the-societal-cancer-of-network-clustering-in-social-media-e2e5e1e5e239
