An upvote; correct me if im wrong; is to be used for liking or agreeing what the opinion poster has said. Yet i've noticed that in some of the questions, every single opinion is upvoted, why is this? does it mean he likes me? (ok that last bits a joke) But for real yo whats going on?
Some people give people the upvote as a "thanks for asking" thing, or to tell them that they read it. I give upvotes to ones I find funny, I agree with, or if I understand where they are coming from even if I don't necessarily agree
