Did you know that you can hide boosts from people? If your client doesn't support this, pester the devs until they either build it in or quit creating the client. The second one is more likely so meh. Anyway, it's really useful.
Mastodon works on boosts. If you see something cool, you boost it. There are no "posts you may like" mechanisms on Mastodon. There are no algorithms. So, if you want people to see something, you *have* to boost. If some one boosts too much, though, you can hide those boosts, especially if you already follow the source they boost from.
