Federation works a little differently. Having said that, it’s not too far from reddit either. For example on reddit, as a basketball fan, I visit r/nba often. But then there are also other subs like r/nbadiscussion, r/nbatalk, and other subs that have overlapping content as r/nba. That’s the same case here, except they are on different instances rather than subreddits. You can do the same as what you do on reddit and subscribe to the most popular instance community and that’s it. Eventually as time goes by, the most popular community will become the “default” so you won’t really miss out on content. If you really have FOMO, then subscribe to all of them; same as what you would do on reddit; but obviously you don’t do that right?
