Open Threads, Media Threads, Rationality Diaries—these are so obviously different from the remaining posts, and they already have a strong tradition, so I believe there should be one subreddit for them (for all the repeating threads together).
More meta: The subreddits should reflect a difference that already exists. One should be able to move the existing articles into the new subreddits. (Moving them would be useful to show readers what exactly is expected where. I don’t expect admins to move thousands of articles, just perhaps the last month to create the momentum.) For example, if you have an idea for a new subreddit, but you can’t list articles from the last two months that would belong there, then this subreddit most likely shouldn’t be created. So as a sanity check, before really creating the new subreddits, we should list specific articles from the last month or two which should be moved to each of them. (Unless we implement the topics using tags/keywords.)
