Encouraging but not enforcing citations sounds good - requiring citations may end up drying up the content wikipedia-style.

The content I'm interested in is twofold - practical/actionable info, and high-level summaries. The former is somewhat covered by WikiHow but their content is notoriously vapid. There's nowhere currently that I'm aware of that I can quickly learn the general mental model for a new topic. If I was new to keto, for example, the article on your wiki would provide me with all the high-level knowledge I need to get started, and to roughly understand what's going on. There are numerous concepts that I want to learn about but often that requires buying 2-3 books or reading a lot of articles before I can start to understand the mental model. Self-help and business books for example are well known for stretching an easy-to-understand concept out into hundreds of pages.
