why do mastodon toots have more boosts then favorites? - Lemmy.world

My understanding is that favorites are equivalent to twitter likes, and boosts are equivalent to twitter retweets, but on twitter people like way more then they retweet, so why is it different on mastodon?

favorite? on the web ui its marked as “save” likely part of the difference you are seeing.

Usually it appears that way (like I was surprised some posts had 0 likes/favourites), but when I click on the post or go to the original source - it shows a higher number.

I just assumed that instances don’t automatically gather likes as readily as boosts.

Because people want that their followers see what theycfound interesting
Favorites are like a nod but not visible beyond the conversation. Boosts make the post available to every one in your timeline. So if you think it’s fun, funny or worth other peoples time you should boost. I usually reserve favoriting for comments on posts I’ve already boosted.
Iirc it’s due to the way federation works. You can see the real number of boosts but the favourites only show the amount from people who are on the same server as you. It’s not reflective of the real number

So, does this also apply to kbin/lemmy?

If a post from lemmy.world shows up on my kbin feed and it has only 30 likes, but on lemmy.world it has 1k likes, I'll never get to experience the real "popularity" of a post?

I’m not entirely sure and I could be wrong, but I think it was for security/efficiency and was not a popular idea. From what I can gather: in Lemmy all upvotes and downvotes are tied directly to the post so it shouldn’t be an issue here
