Now 12 days old, LWiki is still growing. Most of the articles are stubs, but progress is being made. Eliezer confirmed that an official wiki hosted on LW is eventually coming, so be careful about linking to the wiki, but don't let that deter you from adding content.
Standards and conventions are still being hashed out, so jump in now if you want to contribute. There is broad consensus that articles should primarily defer to existing work, either on OB/LW or Wikipedia. However, even quick summaries and links to blog posts can look very different depending on the subject. For example, contrast Rationality as Martial Art and Bias. The former is short and to the point, whereas the latter annotates each link. The latter also makes for much more interesting reading, in my opinion.
Ok, then where do we go from here? The two main avenues of development are creating stubs and then fleshing them out with content. For the first, please suggest any topics, concepts, established phrases, acronyms, techniques, or jargon in this thread that you can think of, and I will be happy to add them as new articles. Or, better yet, feel free to add them yourself.
For the second, I suggest we have a weekly thread that designates one topic for our community to throw its collective intelligence at. That way, we can get all the relevant discussion about the content of an article out at once. For this inaugural Weekly Wiki Workshop, I'm going to suggest the Rationality article.
So, what articles could the wiki use? What should the Rationality article look like?
