A few clicks here or there will not stop the world turning... Master the Zen of HN Vote up posts or comments for the good of HN rather than as a reflex action to something you have just read. In my opinion HN would be a better place without a down vote on comments - the simple choice between an up-vote and no-vote is all that is required - a moments contemplation - a choice made - then move on.
