Do you mean populist? I don't understand your argument otherwise. Popular stories are destined for the frontpage - and the problem is??
I'm not being snarky - I just don't understand your logic. Are you suggesting that HN should only (or mostly) contain posts that we can't already get from more 'mainstream' sites? That makes some sense as an ideal, but would be very subjective & I'm not sure that's what you mean. Please can you expand?
