When I got involved with the United States Project as a Project Leader, I discovered that many U.S counties had free-space pages that had been created with the title "One Place Study," often with very little content. Apparently there had been a misconception about One Place Studies. I think it may have been perceived that any free-space page about a place was a one place study, and members were not aware that counties are almost always much too large to be reasonable topics for one place studies.
More than a few of those county free-space pages still call themselves "One Place Study," but most of them are just pages about the county. I spent a good bit of time editing categories and pages to dispel the notion that the United States project was creating a one-place study for every county in the United States, but many of the free-space pages were privacy-protected and could not be edited without getting access from members who often were reluctant to share the pages they had created.
PS - You've done a brilliant job on that Wilson County page. :-)
