It comes down to your style and what you want to achieve, although if your style is hated by everyone, its obviously saying something.
Personally, I can't stand shots that are mega saturated, along with huge amounts of sharpening. It gets to a point, where yellows end up blowing out, and I see it heaps in farm shots, of hay. The oversharpening ruins an image imo.
i'm far from pro, but most of my good shots, I look at the histogram, see what I've got to work with, alter the levels. take away any colour casts, add about anywhere from 3.0 - 10.0 amount and .35 for radius for sharpening. If I want to soften it up, I put in about 5 and 5 or up to 10 for a selective gaussian blur. I fix any dust spots, no more than +5 saturation, remove any background colours in the way. I reckon if you have a good shot to work with it should take no more than 10 minutes to finish it.
However it all depends on what you are after, I've seen a photo, and I'm about to do one for myself, of a person screaming into the camera, the shot is very dull without editing, but adding a heap of different layers, you can turn it into a freaky photo, ready for a cd cover etc. So I guess it all comes down to what you want with your shots.
