To borrow from the Apple campaign of a few years ago, Southwest proves that it's possible to "Think Different", even in a field as staid and heavily-regulated as domestic commercial aviation. They’re not only sympathetic to their core market’s Red State sensibilities; the airline understands the Blogosphere as well. And in an age of increasingly morose stewardesses, their flight crews are some the friendliest I've encountered.
As Hugh Hewitt suggests, perhaps a much older mass industry could learn something from Southwest's ability to prosper in a tightly competitive marketplace.
