Its been a few years since I've been to any conference, what with unemployment and now working for an organization that doesn't believe in sending any of their IT people anywhere, for anything. But hopefully I'll get a chance to attend a conference again. But the behaviors you've described here, Steve, are appalling to me. Every conference I've attended everyone I saw behaved well. The only wild behavior I ever experienced was when something new was announced from the podium that everyone was excited about. People would then stand and shout out their enthusiasm, but that's it. Sad that bad behavior has happened at conferences or that some people have felt threaten.
