Some people experience their dojos fizzle out and people stop coming after a few times. We don’t think this is because people find the dojo unhelpful or that they don’t need it. Like any community there needs to be a core of more committed people who turn up to every meeting.
The ParisDojo made a rule that if a meeting was arranged, and noone came, then that was the last meeting. period. The idea was to foster a sense that it was everyone’s responsibility to keep it going. Self organization.
The CodersDojoSweden published a list of dates for meetings up front, to encourage people to mentally sign up for a whole semester.
