i hardly consider optimizing a photo for print or web to be overloading on the "salt".. it's a necessity simply due to the inherent differences of the mediums. also.. no matter what, i don't consider HDR to be over processing. if you're setting out to do an HDR project, then you know your vision is gonna require some substantial post processing to begin with. it's a very subjective question, and i think the most objective answer is that all really comes back to the skill of the photographer, and whether they have the ability to create something great to start with.
