Back in high school, someone set up a site for (anonymous) feedback for everyone in class. It took one day to explode and turn into 4chan, so the school administration had to shut it down.
I loved it. It was the first time someone actually told me some of the bullshit I've been doing. (For example, like the people in Eliezer's example, I started showering a bit more frequently. Didn't help that my best friend literally has no sense of smell.) I'd love to get feedback that useful again.
So I'm very much in favor of any such norm or setup. Googling for a bit, the best existing setup I found is whatiswrongwith.me. (Feel free to rant about me). I'll probably look around some more later when I have more time.
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?
