The conversations, before/afters, etc definitely need to include more "normal" people. Otherwise the expectations that are set up are inevitably going to disappoint some people. Not everyone is going to get six pack abs and start killing their own food with Paleolithic hunting tools. A year of clean living, no matter how clean is not going to reverse 30-40yrs of sedentary junk. Hopefully a few years will but for many of us that remains to be seen.
I think the unstated premise in the question (at least as I've interpreted it - could be I'm just cranky from dead lifts and not enough starch in my diet) is that there is a lot of emphasis on the lean and ripped in the community, to the point where it seems to be a bit cliquish at times to those who are not lean and ripped. You can see this in some of the commentary about the AHS this year. From some descriptions of the event one gets the impression that lingering spare tires or sallow complexions would get you stopped at the door (or at least possibly get you noted derisively in a blog later). And the variety of reasons for starting to eat/live this way often lead to assumptions about the reasons others should be doing it and just plain lack of empathy for those who may be starting from a different place (thus comments that those still not being of ideal composition after a period of effort maybe not doing it right or not being "pure" enough).
Personally, I still got that spare tire but it's 6in smaller in circumference than it was. I still have plenty to go in terms of weightloss (down 35, should lose another 20). People do notice it, but the effect that's made the most impression on me is the various improvements in how I feel (no IBS, more energy, in general nowhere near as cranky as I used to be). That's the part I end up talking about to others. It's not the ripped abs (of course maybe if I had them it would be, whose to say), but not having to go sit on the toilet 10 times a day that I want to share. Or just having the energy to participate in life, chase a dog, run up stairs, etc...
In the end, I say it's the health aspects that are most important to share. If you are seeing a big difference in life because of eating/living a more "paleo" lifestyle than please share it even if you do have weight to lose. I don't think you have to be a perfect specimen to represent and I think the community needs more imperfect specimens... or at least in progress ones!
