Also, even though there is no algorithm in Twitter sense, and I don't know whether this is true for Mastodon, but for other Fediverse software such as Pleroma it is: if someone I follow likes the post — although I don't see it on my "Home" timeline, but I see it on global "Known Network" timeline — the instance I'm on at least retrieves the post that someone I follow liked and I can discover it via search or the global timeline, so it still helps post's visibility.
