The Los Angeles Times <A HREF="http://www.eweek.com/article2/0,1895,1952539,00.asp?kc=ewnws042406dtx1k0000599">suspended one of its blogs</A> after discovering that the author used an alias to post material at Web sites operated by the Times and others, which is a breach of the Times' ethical policies. The blog in question is Golden State, which is written by Pulitzer Prize-winning Times columnist Michael Hiltzik. The L.A. Times explained in a "Notice from the Editor" posted April 20 that Hiltzik admitted to using an alias, but wasn't more specific. "The Times is investigating the postings," the editor's note said.
