Some comments are very insightful and are not particularly long. I recently have been reading Roissy's site, and I searched a few terms at LW. I discovered the user Vladimir_M who had some very interesting comments, not only on that front. HughRistik was also someone who stood out. Both of their commenting were very insightful. I am disappointed those people were not on the list.

My other problem with this is that if karma is a good indicator. That pretty much depends on the userbase; I guess we have another thing to test here.
