Can't imagine why anyone would recommend talking to me. I'm just a shit poster in a shit posting world.
What sort of advice could I offer? I can confirm that it puts one at a disadvantage since federation is determined by who follows you. So a single user server will often struggle to federate even if you have hundreds of followers (since a multi user server will have tens of thousands if not hundreds of thousands of collective followers)
I should also point out it is very typical for servers to auto-block single user servers since they suggest no internal moderation.
If I can help answer any specific questions I'd be happy to.
When you do get around to setting it up, or whenever. Feel free to hit me up if i can help with anything.
