I think there are many anti-Bitcoiners on HN. And many of them are pretty agressive about it, which is quite unfortunate.

And probably most people on HN don't know that SN exists or are only slightly aware of its existence.

One big difference to Reddit or Twitter I think is that there is a 3rd small group of HN people don't don't like Bitcoin or SN but still appreciate the elegance of tipping Sats and Lightning. This 3rd demographic doesn't exist on Reddit or Twitter because of tribalism and group-think. But imo there are people on HN like this. They might become Bitcoiners one day.
