Al Silvestri, Hachette Filipacchi Media U.S.'s director-corporate marketing and creative services, arrived for work at Hachette's offices Feb. 2. This is notable only in that less than a month earlier Mr. Silvestri departed Hachette to become Conde Nast Publications' executive director of integrated marketing, where he reported to Conde's Chief Marketing Officer Richard Beckman. Beyond the basics, even insiders are mum, though some insist "it was not a Beckman issue" but rather a cultural clash-and that running Hachette's small corporate-concepts shop was a damn sight different than working in Conde Nast's more sprawling equivalent. Mr. Silvestri did not return calls. Mr. Beckman declined to comment.
