Professionally speaking, that is one of my most important tests of the quality of a site. When I see an Ajaxed site on a resume, it's the first thing I check as it is a sign of a true craftsman taking care in their work.
Ajax should ALWAYS degrade gracefully. Sites that use Ajax just to use it with no real benefit to the end user perhaps for a slight bandwidth savings are a particular irritation. It's often just a strong degradation of the user experience to make up for the deficiencies of your back end, or worse yet for no real reason other than it being the flavor of the decade.
