ok but how about you tell me why to move from mastodon to firefish?
I like the UI better (by a lot), I like the "antennas" feature, I like that I can do a traditional blog post if I choose ("pages" they call it), it's very custom-configurable, and in the 3 days since I've joined I've already seen bugfixes and improvements deployed.
Why move? If Mastodon is 100% great for you and nothing about the look/feel/functionality of Firefish jumps out at you then there is really no reason.
FWIW migrating from Mastodon migrates all your followers automatically and you can interact with them just as you did on Mastodon.
You do need to manually recreate your list of people you follow though, from what I could tell.
Once that's done you haven't really lost anything unless you were or were intended to be heavily active with the feed on your local mastodon instance. (Vs federation etc)
