From the SF Business Times:
PR specialists (also known as flacks) help clients project a positive image to customers, investors and the media. Andrew Gordon, the Bay Area bureau chief of PRWeek newspaper, counts as many as 50 PR firms specializing in technology in the Bay Area, and says new ones are opening regularly.
[San Francisco] public relations firms are re-inflating with the economy. New technology-focused PR offices are popping up around the Bay Area as existing ones expand -- and all are hiring, hiring, hiring.
