Turns out that the Los Angeles Times is not the only media outlet suffering a mass exodus. So is Bloomberg News. I hear that dozens of Bloomberg News staffers worldwide have exited so far this year, and lots more are lining up, especially in New York. The latest is Dana Cimilluca, who covered mergers and acquisitions for Bloomberg News out of its NYC headquarters, according to my “fish”‘ sources (those expensive tropical beauties that reside at Bloomberg’s Manhattan headquarters at 731 Lexington Avenue). Cimilluca is headed to the Wall Street Journal. His quitting Friday caused quite the Bloomberg newsroom stir because he was the only reporter on his team — or for that matter in all of Bloomberg News — who broke any M&A news. Apparently, at WSJ, he’ll not only write for the paper, but also have a blog — something along the lines of The New York Times‘ must-read “Deal” blog done by Andrew Ross Sorkin. Why the Bloomberg mass exodus from all those free snacks and that fancy new building next to Bloomies when so many of their colleagues are looking for jobs? The problem seems to be the, um, difficult personality of Matt Winkler, editor in chief. Stay tuned for the fish to come up for air and explain all.
