One hard thing about building #tagspub is that people get mad that it is needed. A lot of Mastodon users think that following a hashtag on Mastodon gets you *all* of the content tagged with that hashtag from the entire Fediverse. When they read https://tags.pub/#why , or I tell them, they get mad that Mastodon doesn't work that way. But it couldn't! Your server doesn't have access to all that data.
