In many ways, Mastodon feels like rewinding the clock on social media back to the early days of Twitter and Facebook. On the consume side, that means that your home feed has no algorithm (this can be disorienting at first).
Practically, it means that you see only what you want to see and only see it linearly. You never wonder “why am I seeing this and how do I make it go away?”. Content can only enter your home feed via your followed tags or handles and the feed is linear like the early days of social media.
Yes! your fedi client will spit out a text file (.csv format I think) of accounts you follow, or of accounts following you and I forget how many other kinds of information (like block or mute lists, etc). You can share that with others, or if you decide to migrate to a different instance, you can use that in your new account to automate following of everyone you followed in your old account.
