I think you are being a little harsh. Sure it could have been organized better, but I know a few people who went who said other than it being busy, they saw some value in it.
I think it would work better if they limited tickets to a day and kept the total numbers to manageable sizes.
It's the first year they have tried this, putting on an expo of this nature is huge work, and learnings will come from even the most successful event.
Kudos to the sponsors and those who paid to put on a free event.
Some of us actually value our time -- these people advertised that those who pre-booked tickets won't need to line up. The fact that the organisers can't even live up to their own promises is unacceptable. These guys aren't running this as a charity: they presumably get a cut from stallholders/renters. I have no problem with anyone making a profit -- you just shouldn't/don't get to do it at the expense of or via intelligent consumers whom you've given the run around.
These guys are getting the pummelling that they deserve and need.
