One problem with putting experimental #SocialMedia platforms on the net is that there is a high risk of the #DarkPatterns of usage that have emerged in existing platforms, spreading to the new platforms, even if they're thoughtfully engineered to avoid generating them. New social media platforms have to be engineered not only to avoid generating dark usage patterns, but to actively discourage or ideally disrupt them. This has to be as central to the design as decentralization, efficiency etc.
