One step more meta: Should we create subreddits for topics that are discussed there, or rather for the style of those articles? An example of style could be a "Research" subreddit, where you post an article only if the statements it contains are referenced (or if it is self-contained original mathematical research).
An example of a division based on article styles could be:
Official announcements = announcements about MIRI or CFAR activities, progress reports, advertising for effective charities, etc. Written by people from MIRI or CFAR, or by people who have their blessing to do so.
Research = trustworthy articles with references. It is okay if they are written in a less boring style and for a wider audience than the usual scientific articles (this is a blog, isn't it?), but if you say that "X is Y", you better provide some suport for that.
Best articles = no one posts their articles here. The articles here are the selected ones from the following subreddit:
Articles = you wrote a piece of text expressing an idea (not merely a question). It goes exactly here.
Discussion = all the regular threads; plus the articles that merely invite people to discuss a specific topic.
Less Wrong is based on reddit code, which means we can create subreddits with relative ease.
Right now we have two subreddits, Main and Discussion. These are distinguished not by subject matter, but by whether a post is the type of thing that might be promoted to the front page or not (e.g. a meetup announcement, or a particularly well-composed and useful post).
As a result, almost everything is published to Discussion, and thus it is difficult for busy people to follow only the subjects they care about. More people will be able to engage if we split things into topic-specific subreddits, and make it easy to follow only what they care about.
To make it easier for people to follow only what they care about, we're building the code for a Dashboard thingie.
But we also need to figure out which subreddits to create, and we'd like community feedback about that.
We'll probably start small, with just 1-5 new subreddits.
Below are some initial ideas, to get the conversation started.
