I've tried to explain this to people before, without success. I'm starting to think that most people have no concept of what it means to be passionate about something, so they go through life with nothing more than pastimes to keep their minds off reality.
For me it's building boats. I've only ever built 2, the last one 20 years ago. But the amount of time and money I spent on magazines and plans both before and after those actual builds dwarfs the time and money it would take to run a lemmy instance. And now I've got 3 years and several thousand dollars into building and equipping a shop so I can build another one.
I'll throw out a few bucks here and there because it feels like the right thing to do, but I actually want hobbyists, people with a passion for it, running the show. After all, that is what made reddit work. All the passionate mods doing their thing as a hobby.
