If you were going for a social-media-y experience, I'd not recommend Pleroma (or Akkoma which is the less problematic fork) because dealing with Erlang+Elixir is a massive pain in the arse. You'd want GotoSocial[0] (single binary, reasonably straightforward), snac[1] (haven't tried it but fedimeteo runs a whole bunch of instances successfully), or one of the other small servers (Takahē, bovine, etc.)
