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.
There’s a part of me that legitimately wonders how far Twitter could go as an influncer bubble. Granted this is unlikely to happen but if everyone who’s not an influencer just left for Mastodon and Twitter just became a hollow shell of influencers trying to sell products to customers who just aren’t there, how far would Twitter’s inerta carry it before anyone realized?
