The main danger for LW is that it could become rationalist-porn for daydreamers.
I suggest a pattern of counterattack:
-
Find a nonrational aspect of your nature that is hindering you right now.
-
Determine privately to fix it.
-
Set a short deadline. Do the necessary work.
-
Write it up on LW at the deadline. Whether or not it worked.
This was more along the lines of "a kick in the pants" plus anecdotal evidence gathering. Advancement and usage should happen together, for obvious reasons.
