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.
You can have a look here to see a test instance with some of the things that are coming, Ernest (the admin) has been merging in a range of tickets including bug fixes, UI improvements and other bits.
There seems to be an ever growing backlog of feature requests and bug fixes in the issues list but a fair bit is getting sorted out behind the scenes.
I’m mostly focused on UI/UX for mobile.
