I agree with Karin that fretting and obsessing about the fine print is not paleo.
I have moved on from the term paleo in general and (at the moment) subscribe to the label on Kamal's thread--deep nutrition.
That said, "not paleo" probably has a better level of consensus behind it than paleo; to me, it means "not healthy" or "not going to rebuild/promote health." It probably has some use value.
I wasn't going to answer until I got to your question about PH, Eric. I don't think I've used PH to define or even fine-tune my personal definition of deep nutrition. Rather, I've used PH to feel less alone in avoiding processed foods without joining the vegan crowd. I've received inspiration, reinforcement and annoyance but most of the time I have not found it boring. I've found much discussion and consideration of labels and ratios, but I'm not detail-oriented so those aren't really compelling.
My definitions have come from my reactions to Archevore, Gnoll and many others. I'd even use the word principles as my level of commitment is pretty deep.
