I’ve been through a few online communities that tried this (netslaves, plastic) and co-op ended up being “pay me what I would like to run it.”

I remember the shutdown thread on netslaves where the owner asked for money and multiple community members offered to run it or chip in and the owner said no. They wanted the amount they wanted because they also wanted to run their other projects.

I don’t fault them as it’s their site and they can run it as they wish. But just to point out the difficulty of community projects that require money.

Even with food co-ops, there is frequently drama.

Maybe the closest would be to have some sort of online kibbutz.
