This is not a mutual mental masturbation society. People may say things you don't like. People may write stories about parts of the world you don't care about, and may act like those are the only places that matter. People may be rude, although that's not considered good form. People may behave like five year olds. Cope.
Do not rewrite the intro section of a story in the body.
Do not post anything without using the preview button and actually reading, at a normal pace, everything you wrote. Edit it. Grammar, usage, spelling, conciseness. Not everyone speaks English as a native language, and that has to be accounted for, but if you aren't at least looking at what you wrote, then you ARE part of the problem. Odds are I write more skillfully than you do, but I still do this, and you should too.
Do not post to columns unless you know what it is there for. It is for regular features.
Do not post MLP anywhere except MLP. Yes, some MLP is cultural, some is technology related, and so on. It is still MLP.
Do not try to abuse the moderation system to "punish" views you disagree with; this is ineffectual, childish, and often leads others to massively overrate the posts you trashed on in order to give them higher ratings than they would otherwise have garnered. There is a fine line between slamming someone for being wrong on factual matters(the date TWA flight 800 went down,) and on matters which seem factual and may be so, but are legitimate topics of discussion(the nature of consciousness, etc.)
Do not confuse this site with Slashdot. There is nothing inherently evil about Slashdot, but this is not a news site; racing to be the first to post a story about some new discovery or whatever is not the point.
Read the other stories in the queue and in the sections("everything" is handy here) at least briefly before writing a story about some current event, lest someone already have submitted such a story.
Before you post anything to meta, wait a week or two and see if you still feel that way. Most of what gets posted there is poorly thought out, and a bit of time can yield a load of perspective.
Finally, remember, some days, the dragon wins. Learn to lose with dignity.
