So while I want to congratulate the foresight of the people designing the architecture of SSB to prioritise subjectivity (which helps a lot), I also want to notice that, like Loomio, probably the most important reason we're having great conversations here is because there are just not yet many different people interacting in the same space with very different intentions and backgrounds.
When trying to introduce ssb/patchwork to friends, this is among the skeptics they voice up. That is, ssb currently feel good because not much people yet in the network. Once we have spammers, and those click bait posts coming up, it will be no different than the other social networks or email.
