I signed up in 2014, basically the first or second time it hit HN, and over time, I've built out a pretty decent social network on there, and run a dozen or so specialty community chats. I'd be glad to pay them something, 25 a year or so, even if I don't get anything special from it (though, if I did want something, it'd be better access to support if I should need it), just as part of making the service sustainable.
It'd made coordination in my life so much easier, and I legitimately cannot fathom going thru the pandemic without it, it's been my social lifeline.
Mostly I love it because its a desktop has parity environment, I literally sit in front of a computer 12+ hours a day, why do I want to limit myself to a phone-only service.
