I never saw Prairie Home as "small town folks are the real deal". It definitely celebrates small town living, but at the same time it's making fun of the people who live there. Keillor is from Anoka, a fairly large suburb still hanging on to their main street and that's pretty much what Prairie Home is all about. The core audience isn't small town folk, it's suburbanites who still want to hang on to a memory of main street and small town living and laugh about the eccentricities that went along with it. I'm not a huge fan, but I totally get the appeal.
