This post will only really be relevant to people who are using our API, so the vast majority of people can skip this.
We are about to update our API to the closest what graphQL currently has to an industry standard. Starting tomorrow morning (PST), you will be able to find the new API at
lessestwrong.com/graphql for a few days, until we upgrade the main site (probably either on Friday, or on Monday). There is also a documentation for the changes, written by the guy who maintains one of the frameworks we are using (Vulcan), that you can find here.
Sorry for the inconvenience, but it will definitely make the API a lot easier to use in the long-run.
