We are trying to keep it as cheap as possible. $100 bucks for each attendee, which gets them some free food, a comfy seat, and some sort of swag.
Lets be honest with ourselves, the best part of any conference is the hallway track. We want to put diverse talks together in one place to get the most exposure to the most ideas in one day. We want to do it outside of a major city. We want to highlight that while our city is awesome, this is a template that can work anywhere smart and wonderful people live.
