IMO a platform like this has a lot of potential, especially for education. Wikipedia is often far too dense to really learn from if you're not already a subject matter expert.
One thing that concerns me slightly is the presentation of opinion as fact, which to some extent is inevitable in a public wiki that has no citation requirement. There also seem to be articles with a wide variety of intents - there are informative articles like the keto diet instructions and the hierarchy of evidence, but also laundry lists like "no brainers" and "scientific study requests". I don't know if there is an intended purpose for the contents of the site, but having this mix creates some ambiguity in my eyes.
Overall, I'm keen to see where this goes - especially if it can help me to learn new useful ideas and practices (as opposed to edutainment-style wikipedia browsing).
