It unites communities - see the Popstars effect, which provoked total strangers to interact on public transport in order to rage over the unfairness of the exclusion of Warren. And it's also the only cultural subsection that involves the constant makeovers of its leading proponents (see Geri Halliwell, Martine McCutcheon, Madonna). Which explains why it is currently more necessary to be able to talk intelligently about the extraordinary forehead of Dawson from Dawson's Creek, than, say, politics. No one inspired the pop culture moment like Ant and Dec. If they hadn't operated from the start on two levels - a psychotically upbeat, slapsticky one directed at the kids, and an older, knowing, slick-witted level for the grown-ups - we might never have understood the sheer beauty of the love of Kerry (once of Atomic Kitten) for Bryan from Westlife.
