The most common answer I see is something along the lines of “it’s the equivalent of liking a post on twitter”. It seems that this is not the case, as the Mastodon devs seem rather adamant that they don’t want “likes” in Mastodon. Perhaps it’s a method of saving posts? Well, that doesn’t make sense either, since there is already the ability to “Bookmark” a post to save it.
It really just seems like a “Favorite” is just a bookmark that tells the poster, and the public that you bookmarked the post. And even if this was the reasoning – which is baffling enough as it is – it wouldn’t make sense since the whole point of boosting something is to tell the public that you like a post.
It really seems like the “Favorite” button has no actual unique purpose. In my honest opinion, Mastodon should just federate “Likes” like normal, and be done with it.
The person who made the post still sees all the likes.
Unless it’s really important that other people see how much others like you, that’s fine by me.
As much as anything, I don’t want every thing someone else posts that I like clogging my timeline.
