PSA: Upvote is not an upvote like you are used to (like Reddit) - "Boost" is the Reddit Upvote
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.
As a desktop kbin user, there's no strikethrough. Unsure as to why, if kbin is markdown. Strikethrough is considered advanced markdown formatting so I'm guessing kbin didn't include it. Now I'm curious to see how much common markdown is visible on kbin's desktop platform.
Guide for those unfamiliar with markdown, so you can see what I'm doing. ✔ means I can see it on desktop kbin, ❌ means it remains unformatted (formatting characters remain).
