I really like that magazines force you to categorize your posts.
This means that instead of having to add a text filter for "reddit" I can just mute "reddit" and "redditmigration" and a very small number of others.
I truly do not mean this ironically, Mastodon is a mess compared to this, the self-categorization means that I can, if I wish, opt out of hearing about Reddit until after people stop being salty and start posting about astronomy and stars instead.
Mastodon does not force self-categorization so you end up with people using "breadit" or "elmo brusk" or whatever they think is cute and it just makes it impossible to apply a text filter.
