The EA forum (and LessWrong) are both structured primarily as a newsfeed of posts sorted by date. This caters well to immediate engagement, but is much worse for building up a repository of knowledge which is accessible and relevant over a long time period. LessWrong 2.0 has (to some extent) managed to avoid this problem by having a) curated content, so that people don't have to look at literally everything which is posted, and b) sequences which store great posts in a format that makes them easily accessible a long time afterwards. The EA forum has neither. This makes it rather frustrating to try to use it to build on existing intellectual progress, as I recently found out while reviewing forum posts on career advice. Why don't we have any mechanisms for ensuring good content lasts, and what can be done about this? (Even just a blanket 'curate everything above x karma' strategy would help, while requiring very little moderator effort. EDIT: I actually no longer believe this last part, I think the key thing is collating material from across the internet.)
This sentence deserves a strong upvote all by itself, it is exactly the key issue. There is so much good stuff out there, I've read pretty widely on EA topics but continue to find excellent material that I've never seen before, scattered across a range of blogs. Gathering that together seems vital as the movement gets older and it gets harder and harder to actually find and read everything.
I think that's true when there are moderators who are able to spend a lot of time and effort thinking about what to curate, like you do for Less Wrong. But right now it seems like the EA forum staff are very time-constrained, and in addition are worried about endorsing things. So in addition to the value of decentralising the work involved, there's an additional benefit of voting in that it's easier for CEA to disclaim endorsement.
Given that, I don't have a strong opinion about whether it's better for community members to be able to propose and vote on sequences, or whether it's better for CEA to take a strong stance that they're going to curate sequences with interesting content without necessarily endorsing it, and ensure that there's enough staff time available to do that. The former currently seems more plausible (although I have no inside knowledge about what CEA are planning).
The thing I would like not to happen is for the EA forum to remain a news site because CEA is too worried about endorsing the wrong things to put up the really good content that already exists, or sets such a high bar for doing so that in practice you get only a couple of sequences. EA is a question, not a set of fixed endorsed beliefs, and I think the ability to move fast and engage with a variety of material is the lifeblood of an intellectual community.
