I posted some thoughts about this on Facebook, and there's some discussion here:
My most important thought is:
We should not be thinking in terms of "how can the current LW community bootstrap itself into creating a platform that'll enable good content." We should be thinking primarily in terms of "can we build something that Eliezer, Scott, etc would be actively excited to use." (Where "Eliezer/Scott" is a stand-in for "anyone who's currently creating good content in a non-centralized place)
I like some of the ideas in this post, but I think they're emphasized a little weirdly. I think the biggest obstacle we're facing is that the Popular Bloggers like to be able to talk about whatever they want, and they want control over their comments.
A lot of this post (and other attempts) seems to be thinking in terms of "how to restore LW to a sort of Platonic version of itself, where an upvote/downvote system and policy attracts and outputs quality content", and I think that approach won't actually solve the core problem.
(tl;dr: In this post, I make some concrete suggestions for LessWrong 2.0.)
Less Wrong 2.0
A few months ago, Vaniver posted some ideas about how to reinvigorate Less Wrong. Based on comments in that thread and based on personal discussions I have had with other members of the community, I believe there are several different views on why Less Wrong is dying. The following are among the most popular hypotheses:
(1) Pacifism has caused our previously well-kept garden to become overgrown
(2) The aversion to politics has caused a lot of interesting political discussions to move away from the website
(3) People prefer posting to their personal blogs.
With this background, I suggest the following policies for Less Wrong 2.0. This should be seen only as a starting point for discussion about the ideal way to implement a rationality forum. Most likely, some of my ideas are counterproductive. If anyone has better suggestions, please post them to the comments.
