An Oxford comma segue, by John Garrett

From John Garrett of Campaign Thinking, a blog by the corporate practice of Greenberg Quinlan Rosner Research:

"At issue is the curiously perpetual debate over the Oxford comma (a.k.a., the 'serial comma'). You can even see the debate “rage” on its FB page. For those of you who need a refresher, the Oxford comma is that last comma in a series before the word 'and.' It used to be the standard most of us were taught in school, but it has come under attack of late."
