When I visit the root domain I shouldn't be greeted with a marketing splash page, you need interesting content in the user's face right away, entice their curiosity and drive the user to explore the site... even as a fellow developer, my first instinct is to abandon the page as soon as I'm greeted with the cliche startup marketing page. Consider the user experience when I visit reddit.com or news.ycombinator.com or any other link aggregation competitor. What you have now is a tech demo, not a platform. Sorry if that's a little harsh, but I mean well! Good luck!
How about said hook being? "absence of dark patterns" .. which is possible because of stable funding, so there's no enshittification dynamic needed to make money.
Also lesswrong is a cesspool of pseudointellectual bullshit. Eliezer Yudkowsky's ideas don't stand up to reality on average, and the people who "follow" him tend not to understand the relationship between methods of thinking about the world and methods of predicting how the world will behave.
