Discoverability on Mastodon is hard: I find myself using hashtags more to discover people. I'm not aware of any suggestion tools here ("you follow A and B, you might want to follow C"). I'm getting a stream of new followers, which is a great way of finding people, but some users have no toots at all yet.
