What does that even mean in this context though?

The federated timeline is ready FULL of shit I don’t care about, have no idea what it is, or can’t read it because it’s another language due to people not being able to set their language correctly.

The only time I’m going to see threads content is if it is boosted by someone I follow (which I want), contains a hashtag I follow (which I want), or in the federated timeline I already don’t use.

I don’t see the issue.
