David Butler was editor of the Daily News in Woodland Hills until Dean Singleton bought the Detroit News and installed Butler as editor and publisher. That was in 2005. Now Butler has been tapped for another Singleton mission, taking over as editor of the incredible shrinking San Jose Mercury News after yesterday's ouster of editor Carole Leigh Hutton. Butler has recently been vice president for news at Singleton's MediaNews Group and will keep that post, but will relocate from Denver to the Bay Area. The Mercury, once a Silicon Valley powerhouse, has dwindled in staff and local authority since Singleton took it over from the Knight-Ridder chain, via McClatchy, in 2006. Romenesko/NYT
