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.
Proposals for making LW upvote-only emerge every few months, most recently during the retributive downvoting fiasco. I said then, and I continue to believe now, that it's a terrible idea.
JMIV is right to say in the ancestor that subtle features of moderation mechanics have outsized effects on community culture; I even agree with him that Eliezer voiced an unrealistically rosy view of the downvote in "Well-Kept Gardens". But upvote-only systems have their own pitfalls, and quite severe ones. The reasons behind them are somewhat complex, but boil down to bad incentives.
Imagine posting as a game scored in utility. Upvotes gain you utility; downvotes lose you it; and for most people being downvoted costs you more than being upvoted gains you, though the exact ratio varies from person to person. You want to maximize your utility, and you have a finite amount of time to spend on it. If you spend that time researching new content to post, your output is low but it's very rarely downvoted. Debate takes a moderate amount of time; votes on debate are less reliable, especially if you're arguing for something like neoreaction or radical feminism or your own crackpot views on time and dimension, but you're all but guaranteed upvotes from people that agree with you. Plus telling people they're wrong is fun, so you get some bonus utility. Finally, you can post cat pictures, which takes almost no time, will score a few upvotes from people that like looking at their little jellybean toes, but violates content norms.
Which one of these is optimal changes, depending on how tolerant you are of downvoting and how good you are at dodging it. But while removing the downvote option incentivizes all three (which is why social media likes it), it should be clear that it incentivizes the last two much more. You can see the fruits of this on Facebook groups, that site's closest analogy to what's being proposed here. (Tumblr, and Facebook user pages, are also upvote-only in practice, but their sharing and friending mechanisms make them harder to analyze in these terms.)
That's exactly my problem with reddit-style voting in general. Human communication, even in an impoverished medium such as forum posting, is highly, highly complex and pluridimensional. Plus one and minus one don't even begin to cover it. Even when the purpose is a quick and informal moderation system. Good post on a wholly uninteresting topic? Good ideas once you get past the horrendous spelling? One-line answers? Interesting but highly uncertain info? Excessive... (read more)
