Agree with what both of you are saying @therneau and @zakludick using the slider wisely, I try upvote after reading try obtain .02 for upvote, more often than not go back to check VP %, always comment where others take the time to reciprocate.

Reading comments from posts I put up, I try upvote at least two good responses, creating more development in responding and actually discussing various dynamics on topic.

Those who never respond (this is social media after all) I will upvote if I enjoy the content only if it really is well written or beneficial.
