PSA: if you see a remote toot and think "wow that is an amazing toot, why does it have 0 favs/boosts/replies"? It probably doesn't. It's just that nobody from this instance follows someone who fav'ed/boosted/replied to it.
One thing I found useful is to just eagerly follow people you see in the Federated timeline saying stuff you like. You can always unfollow/block later.
The Masto experience gets fleshed out the more you use an instance. Keep in mind toot.cafe is 4 days old. 😄
