Replying to the grandparent, elaborating on earlier information: there's a page on Crocker's Rules in the wiki which you might want to read if you're interested. If you feel that the text is insufficient to get your point across, you could always link to it if you wanted.
I approve of this, and want to encourage this behaviour in relation to, well, everything on LessWrong. One thing I really like about the Sequences and comments here is that rather than explain concepts every time, or assume knowledge of concepts, we hyperlink the concepts to their explanation. It's basically a near-perfect solution to this problem!
Most people need feedback in many areas. Most people can give feedback in many areas. But for some reason I don't see a lot of actual honest feedback happening, neither in my personal life, nor at work, nor here on LW. This looks like some sort of market failure, or perhaps a bug in society.
Would we benefit from a norm that encouraged asking for feedback or critique in any area, perhaps using open threads set up specially for that? I think we would. What do you think?
