When I see a good reply to a question I vote it up. If I can add anything to the reply I will, but usually the standard of reply is high enough that I can’t really add any more. Likewise, if a post is rude, ungrateful or – dare I say it – just plain stupid I will mark it down. I will only post a reply if I feel that the poster would benefit from me telling them they need to be more polite/grateful/smart. Either way, the requirement for me to post would probably stop me voting or make me make a post that would add nothing to the conversation. So I am 100% in agreement with Velaki
