Cross Posted at the EA Forum
At Event Horizon (a Rationalist/Effective Altruist house in Berkeley) my roommates yesterday were worried about Slate Star Codex. Their worries also apply to the Effective Altruism Forum, so I'll extend them.
The Problem:
Lesswrong was for many years the gravitational center for young rationalists worldwide, and it permits posting by new users, so good new ideas had a strong incentive to emerge.
With the rise of Slate Star Codex, the incentive for new users to post content on Lesswrong went down. Posting at Slate Star Codex is not open, so potentially great bloggers are not incentivized to come up with their ideas, but only to comment on the ones there.
The Effective Altruism forum doesn't have that particular problem. It is however more constrained in terms of what can be posted there. It is after all supposed to be about Effective Altruism.
We thus have three different strong attractors for the large community of people who enjoy reading blog posts online and are nearby in idea space.
Possible Solutions:
(EDIT: By possible solutions I merely mean to say "these are some bad solutions I came up with in 5 minutes, and the reason I'm posting them here is because if I post bad solutions, other people will be incentivized to post better solutions)
If Slate Star Codex became an open blog like Lesswrong, more people would consider transitioning from passive lurkers to actual posters.
If the Effective Altruism Forum got as many readers as Lesswrong, there could be two gravity centers at the same time.
If the moderation and self selection of Main was changed into something that attracts those who have been on LW for a long time, and discussion was changed to something like Newcomers discussion, LW could go back to being the main space, with a two tier system (maybe one modulated by karma as well).
The Past:
In the past there was Overcoming Bias, and Lesswrong in part became a stronger attractor because it was more open. Eventually lesswrongers migrated from Main to Discussion, and from there to Slate Star Codex, 80k blog, Effective Altruism forum, back to Overcoming Bias, and Wait But Why.
It is possible that Lesswrong had simply exerted it's capacity.
It is possible that a new higher tier league was needed to keep post quality high.
A Suggestion:
I suggest two things should be preserved:
Interesting content being created by those with more experience and knowledge who have interacted in this memespace for longer (part of why Slate Star Codex is powerful), and
The opportunity (and total absence of trivial inconveniences) for new people to try creating their own new posts.
If these two properties are kept, there is a lot of value to be gained by everyone.
The Status Quo:
I feel like we are living in a very suboptimal blogosphere. On LW, Discussion is more read than Main, which means what is being promoted to Main is not attractive to the people who are actually reading Lesswrong. The top tier quality for actually read posting is dominated by one individual (a great one, but still), disincentivizing high quality posts by other high quality people. The EA Forum has high quality posts that go unread because it isn't the center of attention.
Honestly, my maginal returns of spending time on LW dropped drastically since I finished reading the sequences. Attending local meetups was kinda fun to meet some like-minded people, but they inevitably were far behind in the sequences and for the most part always struck me as trying to identify as a rationalist rather than trying to become more rationalist. This strikes me as the crux of the issue: LW has become (slash might have always been) an attractor of nerd social status, which is fine if that's its stated goal, though this doesn't seem to be the issue.
Additionally, in the 5 years I've been attending meetups (at least six different ones in three different countries), I've noticed a drastic increase in the levels of weirdness happening, to the extent that I find myself discouraged from attending and having to deal with these people. This is the point I think Witness was trying to express below, perhaps not in so many words, but I find myself explicitly not liking a lot of the people/memes now associated with LW. This is not good.
I do, however, think a place for cultivating rationality is important to have, and to that end I would suggest using Github as the platform. Having some sort of rationality repository (preferably without the LW label), where people can open pull requests for things they're thinking about/working on solving. As an added bonus, you get the ability to track how ideas change over time, can easily fork differing opinions, and get all of the cool things a commit history would do for you. I think having some sort of rationality platform is important, but personally I would do away with the LW culture, keep our identities small, and individually go on our way.
LessWrong has had its time and its place, but its lingering death is probably something we should pay a lot of attention to. As a community experiment, I think the results speak for themselves.
