That sounds like a track to me
Thank you for the offer to help out! I guess it will get the best visibility and most interest by making an actual hackathon track out of it (and if not, it’s a complete no-issue to cancel a hackathon track again).
So you’d just think a bit about how to package the expertise you can offer into something that is project-like work for a hackathon (… my first shot would be “collaborative startup concept development”, but I’m sure there are better ways to put it, or more specific ways about the Commons etc.). Works?
