Ways to think about alternative social media

We know the many ways social media platforms are failing us. But/and I think it would be tremendously helpful to expand our vocabulary and thinking about these things to explore new avenues that go beyond the aspects “centralized/decentralized” or “closed/open”.

How about:

• Public Ownership (govermnent-owned, taxpayer-paid) 
• Public Governance (controlled by public through governing body) 
• Public Interest (public interest mission, ownership is secondary)

Does that seem useful as a classification?
