I usually never upvote threads, the same way I forfeit my political right to vote. Maybe it's just autism, but I don't understand why anyone goes voting -do normal people think their vote makes a difference? My one vote will not decide what's on the frontpage and what's not. To be precise: I only see it because it's on the frontpage already and I feel to busy for sifting through new. Actually, I do not believe the frontpage is organic at all. Sometimes you see uninteresting crap with zero comments entering the frontpage, leaving it with... zero or just a few comments. I do sometimes upvote high quality comments and I try to actively downvote and flag spam, which is rare. And I generally upvote people responding to me (unless it's a negative response, which gets a downvote) to encourage giving me responses, as I like to engage.
