While following a lot of people can populate your Home feed significantly, sometimes people (like me) end up boosting a lot and that can unexpectedly hinder your own experience.
So if you like someone's specific posts and don't want to follow their boosts, you can go to their profile under the [...] button, and select the "Hide boosts from account" button.
There is no algorithm on Mastodon. You have ownership and control over every filtering decision instead of some robot.
@antimnguyen @GracelessHippo I want to see people’s boosts, because people’s boosts are interesting; what’s a bit irritating for me is that I’m seeing posts many times as different people boost the same post, repeatedly. It would be nice for an update to know one has already seen a post so you don’t need to see it again,
