Home - Your default timeline, posts from people & tags & groups you follow
Explore/Trending - Shows most boosted recent posts, most used tags, most shared links
Local - Latest public posts from people on your server (also called Live Feeds: This Server)
Federated - Latest public posts visible to your server from across the Fediverse (also called Live Feeds: All)
