I've had a lot of interesting debates in the comment section and I fully agree with the OP. He's calling it skeptical, but I'd say HN is an order of magnitude more skeptical about blockchain than any other topic. I'd pick a much harsher word.

As a blockchain / crypto enthusiast I'm actually unable to have a meaningful discussion on HN. It's gotten to the point where I can't even bother to share my views in the comments as it's not worth it. People are so dismissive and set that blockchain is a scam, that every debate becomes so heated with people reiterating the same position over and over.

So I fully agree with OP - a HN-like community, where people can discuss the non-price aspect of crypto and BC would be nice. I hate reddit and twitter as most of discussions seem price driven.
