It gives me an indication of whether my comments please people or annoy them, and encourages me to keep the two in balance so that my karma stays level.
I have a theory that there's a limit to the human ability to be genuine, and "just be yourself" is not very meaningful, because all interpersonal communication is inescapably an act. Of course you can have sincere intent, and make a great effort to convey what you think is true, but this always has to be done in some kind of register, and so it's always a performance (however simple). Shrek tells us that ogres are like onions, but if you peel all the layers off an onion it vanishes.
Beyond your current self you have room to craft the even greater art-work you aspire to become. The creative effort ideally captures the emotions and experiences.
You are your own composition.
Arguably, judging you should be a privilege reserved for people who know you.
Should civilized men engage in this assumption that everyone is easily understood entirely by written words or does the act describe how shallow the jury is?
I'm sure I have much to learn from people down voting my comments without saying anything.
If only we could all be more like them, then we wouldn't need to have these conversations. haha
