I have found a pretty similar thing on a lot of the other paleo websites....but a quick google search will show that the overall acceptance of paleo has gone through the roof. With the addition of Crossfit pumping it up, seeing it commonly in papers, it has hit a place of widespread understanding of what it is, relative to a few years ago.
This all said, this particular site does not have the number of posters it used to. At times that can be frustrating, but for me I didn't always like it back then. What you ACTUALLY had were about 5-6 people that posted about a dozen times a day, at least. What this meant was that any and all discussion was taken over by them, an OP was usually ignored, and they would spend the next 17 pages of threads trashing each other.
Most of these posters are no longer on here. When I look at the number viewing though, it is almost always in the same area I always remember it as.
And even if MDA went down totally tomorrow, it does not speak to the broader trend of paleo growing exponentially. My local bookstore has an entire bookstand (there are maybe 3 in the whole store. Another has ALL of the "Divergent" books) that is nothing but paleo/ancestral books. 2 years ago, that wasn't going to happen.
I just wish a lot more people that view would post. It would really help the discussion.....all the while though, it is just a truism that the kind of person MOST likely to do paleo (younger,educated, active, outdoorsy people according to many newspaper articles) is ALSO the least likely to want to post on an internet forum of any kind. It's just the reality.
