Niche social networks are easier to get traction with today than at any other time in the past decade. Vast numbers of people are turned off by the vile major networks like Twitter and Facebook, which are overflowing with hate, calls to violence, constant threats, psychotic mobs that will try to ruin your life over basic disagreements, and so on. The future of social media - where the best experiences will be had - is in niche communities that are heavily insular and can easily blockade against terrible users and their terrible posts.
