So if I go to the euroko 2012 in Berlin, pay 50 euros and no hotel, airline etc. and get to see speakers and attendees from all over the world, including Yukihiro Matsumoto for the keynote, that doesn't count as a conference because it's local and organized by a crew of volunteers that don't need to reek in hefty profits?

So you can choose to quote your 50 euros and say that it's a conference, or you can examine how much money the "attendees from all over the world" paid in travel and hotel paid in and note that their money is now being substituted by the web.

Your call.
