Everything to everyone is not nearly the optimal learning environment (see my post on The Unbundling of Reddit). Udemy prides itself on its vast catalogue to "study any topic". But, vast has passed. As the internet is becoming increasingly bespoke, we crave smaller, more thoughtful communities.

Education 3.0 created companies that were designed to replicate the social experience of college, a book club, or group class online. Part of the fun of learning a new skill is the social aspect, which is lost on 99% of edtech startups who think too transactionally and — dare I say — too efficiently.
