I found the line “For the most part people are fairly well behaved”quite a damning statement.  I’ve only been to UK conferences, a few SQL Saturdays and SQL BITS and never seen behaviour that I’d consider a problem.  When there’s been technical problems, people (including me) have left sessions and spoken to the organisers about them, but I’ve not noticed any confrontation.

I’ve not seen a lot of what goes on behind the scenes, but even so, I’m surprised that there are as many problems as is being implied.
