Good!
No. Not good. It damages the signal to noise ratio. LW normally has a very good ratio. Having every single stray thought show up like this is not increasing that ratio. While you do sometimes have interesting ideas, you are not bright enough, informed enough, or a careful enough thinker that we gain much from a not highly censored stream of your thoughts.
For the rest of your reply, the fact that people can't do something perfectly doesn't mean they can't do a useful approximation, and it doesn't mean I should interfere with attempts to get the best estimates they can. If my ideas are generally good, then they will pay attention and that's a good thing. If my ideas are not worthwhile then people will stop paying attention and that's a good thing then also.
That's the Cooperate-Cooperate equilibrium. In the broader intellectual world one can make an argument against unilateral disarmament in self-promotion (particularly if others engage in it for quite different reasons). OTOH, the C-C equilibrium is better, and LW is closer to it, thanks in significant part to LWers' negative reaction to self-promotion.
Thank you for your cooperation and understanding. Don't worry, there won't be future posts like this, so you don't have to delete my LessWrong account, and anyway I could make another, and another.
But since you've dared to read this far:
Credibility. Should you maximize it, or minimize it? Have I made an error?
Discuss.
Don't be shallow, don't just consider the obvious points. Consider that I've thought about this for many, many hours, and that you don't have any privileged information. Whence our disagreement, if one exists?
