Dick Costolo's new job

San Francisco

THE former chief executive officer of the beleaguered social network Twitter has a new job that some might view as a promotion - a contributor to the writers' room on HBO's hit show, Silicon Valley.

Dick Costolo, a one-time stand-up comedian, says he's spending a couple of days a week working in the writing room for the third season of the tech-industry parody show. "I'm in the writers' room, and it's more consulting than writing. There's plenty of writing talent in the room," Costolo wrote in an e- mail. "I'm answering questions and describing how interactions would work between executives, VCs, employees, etc."
