I'm not the one who downvoted you, but if I were to hazard a guess, I'd say your were downvoted because when you start off by saying "people like me", it immediately sets off a warning in my head. That warning says that you have not separated personal identity from your judgment process. At the very least, by establishing yourself as a member of "people like me", you signify that you have already given up on trying to be less wrong, and resigned yourself to being more wrong. (I strongly dislike using the terms "less wrong" and "more wrong" to describe elites and peasants of LW, but I'm using them to point out to you the identity you've painted for yourself.)

Also, there is /always/ something you can do about a problem. The answer to this particular problem is not, "Noobs will be noobs, let's give up".
