The Reddit thing is reasoning by anology at best because the argument is that curation is key to stop useless things from becoming popular. You're also completely shifting the Reddit thing from what you initially said it was supposed to show, from "curation key to stop LessWrong to becoming Reddit" to "it shows why curation is important", where the reason it was important was "because it stops Reddit" but yet you conceded that the reason it's important is not "because it stops Reddit", there's an implicit contradiction. All Jeff's article says is that memes aren't productive. Rude things aren't inherently unproductive. And 1/3 negative karma means that we would get rid of many productive things, so more downvoting is still an awful idea.
Below stuff I agree with, except I disagree with Emile about the intensity of karma sinks, I think the effect is pretty strong. Personally, I'm experiencing some, and people are going around hating on everything I do, which sucks. Karma sinks are where people are more likely to downvote things that have been downvoted. It's like the Communism example I gave earlier in a few different ways.
I don't think you're correctly using the phrase "karma sinks." Or at least, you're not using it the way I see it is typically used on LW. Karma sinks refer to comments users make in order for other commentators to purposefully downvote if they upvoted another specific comment. This is so we can do things like straw polls without the polling user gaining tens or hundreds of karma.
That might be unclear, so I'll give an example. I recently made a comment asking whether people would be interested in a New Jersey meetup. I could have also asked those ...
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 85. The previous thread has long passed 500 comments. Comment in the 15th thread until you read chapter 85.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
