You have the “explore” tab which is more like “today’s viral toots” (which tend to be a lot more varied than Lemmy’s “All/Top 24h” since Lemmy is a link aggregator and doesn’t really lend itself to jotting down thoughts or diatribes), and you have your personal timeline which is people you actively follow. It’s not a cafeteria, it’s your RSS feed.

Where it gets shouty is in replies, especially as those get federated weirdly. But that’s only a problem for the few percent of users who are making content, not for consumers.
