The April 18th issue of Now I Know had, in the bonus fact, a link to a page on Wikipedia which housed an unfinished portrait of FDR. According to my Mailchimp stats, I sent about 10,000 clicks over to that Wikipedia page. I told a couple people and the reaction was a mix of “wow!” and “are you sure Mailchimp has it right?”
And then I remembered that you can check the page traffic on Wikipedia entries.
So I did that. It’s above. Mailchimp had it right.
