I don’t think that startup will succeed to the same degree as Wikipedia. Making an successful online encyclopedia isn’t a tech problem, it’s more of a community problem. And it’s stupidly hard to maintain such a vibrant community, moreso if for-profit entities are involved. I’ve seen so many cases where the contributors leave the website due to clashes with corporate members (see StackExchange for an example) In a for-profit service where content is made by contributors without any pay, there’s an inherent power imbalance between the contributors and the platform owners, and it’s natural that tensions will arise.

But what if it did succeed?
