For anyone interested in a little context behind the organisational effort that goes into this event, William Osman (the genius brain behind Open Sauce) has put up 12 short videos documenting his attempts to promote the event in the week leading up to it.

I feel like everything about this event is about quality over quantity which is incredibly rare these days & likely what most participants & attendees value about the event. Adding a lot of professionalism to it is going to dilute that aspect.
