The lesson you should have learned is to make the generic landing page actually describe the what the product attempts to acheive! You have just had a load of inquisitive wanting-to-be-impressed HNers descend on your page and nobody knew what the thing was about! :)
Publishers, educators etc also need to understand what the value proposition is for their users.
I also think the page ought to be written in longer sentences. The current silo buttons aren't even making it clear that they explain more.
So, suggestions:
You just have to take the few sentences from your Individuals page "Reading on-screen can be tough on your eyes, especially if you have to do it all day long. We’re here to help. BeeLine Reader makes reading on-screen easier, faster, and more enjoyable." and put that on your landing page instead of "A New Way to Read."
Now change the "(choose)" subheading to "perspectives:", put it lower nearer the buttons instead of near the description, and perhaps left-align it.
Change the buttons from meaningless colours with labels to something descriptive like "for you the user :smile:", "for the publisher $" and "for the educator :graduation-hat-icon:".
Voila! good luck!
