BarCampMelbourne is an open, participatory, not for profit event run for technically minded people.
BarCamps are unconferences – gatherings of people who come together to share information, knowledge and experience in a friendly, laid back environment. BarCamps are participatory rather than passive events – attendees are expected to present, to share and to contribute to the event. In this vein, the agenda for the BarCamp is set on the day, through a tradition of attendees who wish to speak writing their topic on a post it note. The post it notes are then combined into streams.
Attendees then choose which presentations they want to see – this is the 'rule of two feet' and helps to ensure that people get the most out of BarCamp. Presenters who don't have a huge audience are not offended in the least – as attendees are learning what they wish to.
The behaviours discouraged at BarCamp are those such as excluding or belittling others, not participating, or detracting from others' presentations.
