When Business Insider’s Joe Weisenthal became known as one of the hardest working people in finance journalism through a New York Times profile that followed him through all seventeen hours of his work day last year, he was the site’s lead financial blogger. Now that the site has expanded to the point that it needs an executive editor, Weisenthal’s going to be taking on that role, The Times’ Brian Stelter reports, while founder Henry Blodget maintains the editor-in-chief position. Weisenthal “described the new position as an extension of what he already does, editing articles and helping to set the editorial direction of the site,” Stelter wrote. For a guy already in the habit of starting work at 4 a.m. and knocking off at 9 p.m., an extension of duties sounds like a terrifying prospect. Weisenthal says he’ll write a bit less but since he “can’t imagine slowing down on Twitter,” where he cranks out some 150 missives a day, that mostly leaves sleep to suffer.
