It's a long read but it's very interesting. I think pretty objective too. I liked the statistics compared to the census and polling data. I've always held that the "16,000,000" or whatever the count is for the Memorial is reflective of inactive and DF'd plus the publishers and kids. I don't think that a very large part of that number is interested ones at all.
When I went this year, I don't remember seeing that many new faces. It seemed like less then 5%.
