It was counterintuitive to me at first, but IIRC the idea was there were too many people talking, and they wanted to have discussion driven by creators, or people with at least some amount of clout that a friend would personally refer them for comment access.  It spread in&#x2F;around our local accelerator here.<p>There&#x27;s a podcast episode maybe a year ago with Erik Torenberg (co-founder) where he discusses in more detail.  He also talks about focusing the communication by splitting PH into verticals for games, books, etc. as it is now, but at the time it hadn&#x27;t happened yet.
