Far too many, I believe, are competing against every other submitter here and won't upvote anyone else for fear of being beaten by another. Also, there are those that don't want certain others to succeed at all. I realize that I am never going to be number 1 overall and don't mind if others do well. I upvote humor, information, and pithy comments. I also regularly search out the posts of people I follow and upvote them because they have already proven to meet the requirements I have set for the upvote process and do not fail to produce upvotable content on a regular basis. 😌😊👍
