Look at what you do when you see a flaw, but from someone else's eyes. If the next paragraph does not fit what that person sees, this post isn't addressed to you.
"So SkilledMcSkillface joined my server, and insulted my work because of some easily overlooked flaws that someone new to that field wouldn't know about or realize was a problem. Then, he pushed some way to 'fix' the problem which actually just made it worse, and when I tried to explain this to him he got all condescending and told me I was 'doing it wrong'. Man, that guy's a richard."
Yes, perhaps you are better at something than others you know. Maybe you're even among the best you know. But that doesn't give you any right to act like a richard to others just because they are doing something wrong, especially since you yourself made or could have made that mistake at some point. You don't have any right to be a condescending prick to others just because they make mistakes that someone at their skill level is at. Imagine pointing and laughing at someone in kindergarten because they're still learning the alphabet.
Does that seem right to you? If the answer is yes, you need to see a psychiatrist. That's basically what you're doing when you call people trying to learn a field morons because they made a mistake. Now imagine laughing at the kids in kindergarten, then showing them how to write an R properly. And as you walk away... you realize you just wrote an Я. You can't really make a more fundamental mistake, and you with all your experience in writing letters just made it.
Basically, my point is this. Having that not everyone does doesn't make you a god. You're still a human being and should treat others with the same level of respect that you would wish to be treated with. If you want a good idea of what it's like to be a bottom-of-the-chain scripter/modeller/builder/eventer trying to learn how to get better in this community, take an hour out of your day and imagine a world where everyone punches you in the face when you walk by, and if you try to punch them back they shoot you with an RPG. That's roughly what it feels like.
And at the very least, have the humility to not continue trying to act high and mighty after you realize you wrote an Я instead of an R.
