I was confused on what they were trying to accomplish, and even after reading the article I am still somewhat confused.

Instead, when a user posts something, the algorithm automatically reads the content and tags it with relevant interests so it shows up on those pages. Users can turn up the serendipity slider to branch out beyond their stated interests, and the algorithm running the platform connects users with related interests.

Perhaps I’m a minority, but I don’t see myself getting much utility out of this. I already know what my interests are, and don’t have much interest in growing them algorithmically. If a topic is really interesting, I’ll eventually find out about it via an actual human.
