One thing, thro', is the missed opportunity to have a Melbourne Declaration or Manifesto of some sort. I flagged the idea and here is the first draft (with help from the gentleman sitting next to me):
We, atheists meeting at the Global Atheist Convention at Melbourne, 2010 declare that:
(1) we celebrate reason,
(2) we treasure evidence, and
(3) we find all accounts of supernatural beings contradictory, without evidence and unbelievable.
