Piper on Fine versus Folk Culture

At our last Tuesday night "Show Grace" Bible study, we discussed the differences between folk, fine, and pop culture as detailed in Mark Driscoll's The Radical Reformission. John Piper offers some great insights on culture here by pointing out the differences between those fine and folk. Piper seems to conflate pop culture with folk culture. I think Driscoll's three-tiered distinction is more helpful. But Piper's thoughts are excellent, regardless.
