NEW YORK Manhattan gossip columnist Liz Smith, who knew her way around a blind item long before today’s celebrity bloggers were born, is no longer a New York Post columnist, due to financial considerations. Her last Post column will appear this Thursday. Starting next week Smith will move her column to women-celebrating Web site wowowow.com -- of which she is a founder -- marking the first time in 33 years that Liz Smith’s column will not be in a New York newspaper, according to the site.
