I routinely use Google to find people talking about me online, both out of curiosity and because I sometimes want to respond. Recently I noticed something odd—lots of posts that mention my posting on the subject of obesity and rising incomes, always with that wording. I found nine hits today for the search string ["obesity and rising income" Friedman] and suspect the figure would have been higher if I did the search a few days earlier.
Searching this blog, I found no articles with that title, so went to one of the posts that mentioned it, followed its link, and eventually reached a post I made back in 2007 entitled "Obesity: A Conjecture." Further searching found someone else's post, made a few days later, that used the phrase "obesity and rising incomes." But I do not know how references to an old comment on an old post of mine suddenly become the topic of the day.
Any guesses? Did some very widely read web page have a link to the old comment sometime in the past few weeks?
