Yes! I think a key part of interacting and making a worthwhile contribution is being a careful reader and fully understanding the post before you comment. Being able to give specifics about how you agree or disagree makes for better community and better understanding. If another user disagrees with one of my comments and they have a clear point of view with specifics backing it up, I will usually upvote them and then tell them why I think they are wrong. Mind you my 100% upvote is a full ¢1 so it might be taken as an insult. Although it is meant to say thank you for listening to me and for giving me a clear response of how you feel. This is the kind of interaction that will benefit the community and make us grow! Papa knows best!
