Eh, with user links, user commentary, profiles and votes HN is "basically the same" on several key aspects and there is quite a bit of demographic overlap. It's just reached a very different equilibrium as to what goes on here due to the 2nd and 3rd tier aspects that are different.

Take two cesspools (I'm not gonna pass up the chance to use the analogy, sorry not sorry). Assume they are both serving the same quantity and quality of people. Feed one a bunch of inorganic matter, laundry bleach and only the finest most heavy duty multi-ply shit tickets. Feed the other nothing that shouldn't go down a drain, no bleach and Scott 1-ply. The latter will perform way better and go way longer between needing service despite the only differences being minor differences that don't even matter in system design.
