I'm not sure what you were disagreeing with, but I have to disagree with your disagreeing because if 5/11 people crashed the thing in an hour, it's completely unusable for many people, me included.
When someone says "pulseaudio 2.0", they mean it in a derogatory sense ;)
Also, the statement about Ubuntu being less stable than debian testing. I don't know the GPs specific instance, but Ubuntu has basically made debian a usable desktop.
When ubuntu first switched to pulseaudio it was apparently a big mess, and the "fix" was basically to uninstall it. So, calling Unity "pulseaudio 2.0" implies that the first thing everyone will want to do is switch from unity to "classic" GNOME because Unity is too buggy (right now).
As I understand it anyway, I wasn't using Ubuntu Desktop by the time the pulseaudio thing happened.
