Conceived in San Francisco 42 years ago, the publisher of Rolling Stone has decided to close its cozy SF office at 1700 Montgomery due to cutbacks. Founded by Jann Wenner way back when, this most recent snip to the ailing music mag (Rolling Stone is down 21.6 percent in ad pages for 2009) is slight but significant. According to Portfolio, "a Wenner spokesman confirms the shutdown but says only two employees were laid off as a result; a third staffer who worked in the office, an ad sales rep for Rolling Stone, is relocating to Los Angeles. Said spokesman goes on to say, "the business just is not in San Francisco now." Well then.
