I just checked how much it costs to attend OS//OS this year. I'm not sure if the people setting the prices realize this, but the unwaged/ student price of $234.70 is more than a week's income for most people on a benefit or student allowance. For anyone living outside of Welly, there is also the costs of travel and accommodation. Only people who are already passionate about open stuff could even consider paying this, so by setting the price of attending this high, we will almost certainly be preaching to the choir. In other words, there is a massive missed opportunity to share open/ libre/ commons principles and practices with the wider community, which is a real shame.
Have you looked into livestreaming the sessions, like NetHui have done, so kiwis who can't afford to attend can still benefit from the amazing programme of speakers and workshops you've put together?
