A reminder that Mastodon has no algorithm that pushes posts favorited by others. This is a fundamental difference with the way Twitter works. If you like a toot and want others to see it, the best way to do that is to boost. Favoriting a post helps the author know you liked it but doesn't do much more.
@dangoodin mastodon does have trends, and favoriting posts increases the trend score, so it does a little more than just send a notification to the author :p
it's not like twitter where it will shove things you like in other peoples' feeds, it's just... good, actually. favoriting posts should be encouraged!
