Have you read the comment sections on right wing blogs? Mostly awful.
The average comment isn't too great on LW either.
We have recieved substantial feedback via that mechanism already.
And whatever feedback you have received, you would have received even more feedback. Nupedia vs Wikipedia - wait, is that example so excellent that you don't even know what Nupedia is? Closer to home, then: OB published everything sent to it, yet Eliezer discovered when LW was turned on that this 'trivial inconvenience' was inhibiting countless posts and submissions.
For example, I've told you on IRC how I think the tribalism post is bullshit, but I have zero interest in writing up an email and sending it off and the email either never being seen or at best quoted.
The letters to the editor system is superior to moderated comments when it comes to optimizing for high signal to noise ratio
And you've based this on careful experimentation, of course.
OB published everything sent to it
The one post I sent to OB was rejected. (Which it deserved to be, since in retrospect it was pretty poor.)
Various people (including Konkvistador who has been talking about it the most) have launched their blog More Right
"A group blog, More Right is a place to discuss the many things that are touched by politics that we prefer wouldn’t be, as well as right wing ideas in general. It grew out of the correspondences among like minded people in late 2012, who first began their journey studying the findings of modern cognitive science on the failings of human reasoning and ended it reading serious 19th century gentlemen denouncing democracy. Surveying modernity, we found cracks in its façade. Findings and seemingly correct ideas, carefully bolted down and hidden, met with disapproving stares and inarticulate denunciation when unearthed. This only whetted our appetites. Proceeding from the surface to the foundations, we found them lacking. This is reflected in the spirit of the site."
