How much formal training does the author of the blog post have? From the short bio, it doesn't sound like much. That said, my training -- read Friedman's intro text in high school (just freetime reading on my own -- so not formal per se). Two quarters of stats as an undergrad. Two quarters in grad school. All of which at least 15 years ago -- so mostly forgotten anyways. :-)
