The market is rife for a new kind of social network, one that is secure, free of misinformation and bots, and community-driven. Not sure if Mastadon is the answer but I do have faith that the tech community can rally to put something next-generation together.
I am interested in Jack Dorsey's "Bluesky" technology which pivots from platform-adherence to content creation independence, and decentralizes social networking hosting.
Additionally, I think platforms need socially-responsible objectives. Particularly, industry self-regulation and standards implementation across platforms is long overdue. Here is an academic paper by Nina Brown at Syracuse University about the need for such industry regulation and what that might look like:
