More interested in celebrity coverage than substantive beat reporting, Hofmeister exhorts her showbiz blog staff to?try to have "an original thought" from time to time which?"readers can use to sound smart in a meeting or cocktail party". Isn't it swell to be so trivialized, Hollywood??By the way, several current?LA Times entertainment beat staffers have approached Deadline about jobs recently. They don't?want to work anymore for Silly Sally.
