Nobody truly rational will lay them out for you.

?

"Truly rational" people don't share information on instrumental rationality with others?

A rational agent will not post information that reduces his utility by enabling others to compete better and, more importantly, by causing him any effort unless some gain (status, monetary, happiness,…) offsets the former effect.

Perhaps people are finding that benefit. How long have you spent considering what those benefits could be? How many people have you asked what benefits they think they receive in return for their effort?

LW is great if you have an IQ of 140 and are tired of superficial discussions with the hairstylist in your village X.

LW is great! Yay!

But keep in mind that the instrumental rationality of your hairstylist may still surpass yours

Perhaps. But how is that relevant? I'm not my hairstylist. Different attitudes, preferences, habits, and aptitudes. Do you think that what works for "your hairstylist" is likely to work for LW readers?

Yes, LW did not make me omniscient and omnipotent yesterday. Did you think I thought otherwise?

LW sucks, compared to what?
