Personally I am surprised how anti-billionaire HN is given its run by a venture capital company and its aim is (indirectly, through reputation building and PR), to get wanna be billionaires to raise capital from them.
I don't think this forum has significant costs of running, especially considering it is not in development.
It didn’t use to be this way but through evaporative cooling, most of the founder types stopped posting here.
It's partly explained by all the non-US contributors here. That's my theory.
Of course, billionaires are unpopular even in the US. Yet, as sparsely attended at that (earnest!) pro-billionaire protest in San Francisco was, I find it totally unimaginable that that could happen anywhere outside the US.
