So I don't know enough about the inner workings, but on Reddit I never browsed all at all - it was 100% communities I'd subscribed to. At the moment I'm happy with Lemmy All, but if in the future when content gets too much, would I say, be able to host my own instance in my Android device and my subscriptions will just pull in the content I'm interested in? That way I am not putting load on other instances, and I can take my configuration with me without needing a cloud service?
