I do actually "spend" my votes on HN; I very rarely downvote, and I only upvote if I think an article or comment is too far down the list. HN is the only online forum in which I participate at the moment. My vote isn't really "spent", because I don't have a vote budget; but I do have an attention budget, and I'm certainly not going to vote on an article I haven't read.
