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.
Your level of engagement with the community is absolutely spectacular. I’m glad to have found myself a cozy little Internet space and wish you the best of luck with this one hell of a side project!
