>3) HN is 3 years ahead of mainstream, but 10 years behind the edge I think you're using a weird definition of 'edge' here to mean "things that nobody else knows about" rather than the cutting edge of the industry/academia.

If you want to include things that aren't public, that's super vague and sort of pointless.
