My view is that unless you're doing forensics or are a photojournalist, how much you do is up to your personal vision. There is no right or wrong, and most importantly, you're not going to appeal to everyone no matter what you do. I think this is good in that, if I were trying to appeal to everyone, it would mean I was making too many compromises to my own vision.
What is clear is that EVERY image is manipulated to an extent, even SOOC images could be manipulated by adjusted exposure and use of filters. With digital photography, an image only is realized to its fullest potential with some judicious post-processing. It's part of the deal. Again, to the extent that you use each step or tool is up to your personal artistic vision.
The only caveat with the SOOC images is that I do try to duplicate my pre-visualized or desire for the image as much as I can with the camera--if only to make things easier when I get to post-processing. I believe that you can tweak and improve an image to get it the way you want. I don't believe you can "save" or "create" a good image if you mess it up when capturing it--at least most of the time.
When I do come across someone boasting that their image was straight out of the camera with no post-processing, my first thought or response is, why? Why would you present an unfinished image.
