Ah, Cindy and Liz. The Post’s divas of dish are finally responding to critics who note that they only write about dead people, or ones that are getting near dead. Today Liz Smith indignantly begins a column about Elizabeth Taylor with a potshot at celebrity whippersnappers. “Today people seem to think ‘the famous’ are Paris Hilton, Britney Spears and their ilk — young fools who shot to the top via the paparazzi, with little attendant baggage to keep them afloat.” She explains that Taylor is “truly famous” because of her Oscar wins and philanthropic efforts. Mm hm. That’s all well and good, but Liz misses the point — Elizabeth Taylor lives quietly at home and hasn’t acted in anything since 2001. Britney and Paris have been flashing their junk with regularity all summer — now that’s relevance. We think Cindy Adams put it best when she wrote, yesterday, “I realize this column is mainly about people who died.” Only in New York, kids, only in New York.
