I'd put Chris Masterjohn in the original big 3 and take Kurt harris and put hims somewhere else. Harris showed up may 2009 i believe, while Chris has been doing this at least on his website since before 2008, and written many articles for the weston a price foundation even before that.

Also I have a personal bias since it was Chris's, Stephan's, and Peter's blogs that go me into this whole thing. other than that this list seems pretty accurate
