@librenews I'm trying to not use the established product categories because they are just labels that we got used to, but instead to describe the characteristics of the communications structure.

One reason: if we think of the fediverse as social media, we automatically fall into the bucket defined by Twitter and the like and it's hard to think outside of the category. If we think what kinds of communications there are, it's easier to say "why is x and y not in the same product", for example.
