Like the title says, if you want to upvote something on KBin, you should use the Boost link, not the upvote button (Why? Don’t know…)
The upvote button doesn’t seem to do much, but Boost accomplishes what Reddit’s upvote did. So if you’re looking to encourage a post, use the Boost link.
Although the name “boost” is a little odd. kbin is more than than just a link aggregator. kbin is also a semi-blogging platform (View the microblog feed rather than threads) that interacts with Mastodon. If you boost something, it is the same as reblogging (re-tweeting) a post and generates a reblog post on Mastodon. The developer is going to change it to where the up and downvote impacts reputation rather than the current boost and downvote button. A technical oversight but they acknowledge this and plan on changing it in the future however internet points is not really a priority so no one knows when the change will roll out.
This finally made it make sense for me. Thank you
This is the answer.
