Which creates hard science and C++ reddit communities at the expense of a general reddit community ("reddit" is an epithet here), when the general HN vibe is the reason many of us are here.

Aren't exclusivity and selectivity the very goals we seek? And isn't HN becoming truly popular and thus generic and shallow exactly what we seek to prevent?
