I have a question about how federation works, and I feel like I probably asked before so either I didn't get an answer or I got one that didn't "stick."
How does it work? I see a lot of "please boost this post so my instance can federate."
Does that do it? Or does someone from another instance have to FOLLOW that person to get them federated to that other instance?
Or is it enough for that person on the new instance to start following folks on other instances?
I really thought it had to do with the following part, not the boosting part.
