I don't get it.. So far I've been able to add anybody on Mastodon. I'm on indieweb.social, but most of the people I'm following are elsewhere. Seems to work fine. Yes, it isn't spoonfeeding me contacts or content like Twitter wants to, but that's also a good thing. I see a lot less bullsh*t.

Also almost nobody I've come across actually says "toots" -- they just say "posts" :-)

The equivalent of the FidoNET nodelist would basically be whatever the most popular Mastodon servers are choosing to federate with. It seems in practice to be more of a consensus driven thing, but has the same net effect. We'll see if it scales.
