What is this, then? It’s on the front page of a Mastodon server before you log in and afterwards the discovery section with posts, hashtags, people etc. is on the search page after login. Bluesky was far harder to get a decent feed going on till people started building lists (and those are pretty flawed in that you only follow the individuals - not the list - so it doesn’t update for subscribers).

Lots of little things that add up. Some of the better include temporary muting, hashtags, and hashtag subscriptions. Plus it is resilient with no single point of failure.

Mastodon has far more features. What it doesn’t have is centralization.
