So. We're starting a "worker cooperative" of sorts to work on medical informatics projects. We're calling it Mechanical Rabbit. Right now, we're focusing only on open source software: https://github.com/MechanicalRabbit/
The Drivers Cooperative (https://www.drivers.coop/) is at the top of Hacker News (https://news.ycombinator.com/item?id=26588607) -- I've never seen a platform coop at the top.
