I am more confused with the upvote and down vote buttons on kbin: the upvote is actually favorite, the equivalent to reddits upvote is boost, the downvote seems not to have a real function besides counting the number.
TIL... I've been using the upvote the same as I did with reddit.
I've not been able to wrap my head around reputation points either. I've made several comments, a couple of posts, and my reputation has gone from 0 to -1 to +1 to 0 over the course of the week I've been here.
