@aral Thanks for sharing.
Traditionally the concept of Dutch hacker camps was: everyone is a volunteer & everybody has to contribute to the camp incl buying a ticket. In that sense it was different from conferences. My first one in 1997 even had a communal kitchen, dinner was included & afair everyone helped out incl speakers. It was a community effort.
This spirit is still alive @why2025camp, but expectations, people, prices & the world has changed. Maybe the camps should adjust to this?
