Twitter Nabs A Longtime Facebooker And Yelp’s First Salesperson To Drive Ad Sales

" We're planning to ramp up the advertising platform ," Twitter writes in an email today. That shouldn't be too surprising, but they're also announcing some key hires in order to make that happen. Dan Coughlin is joining Twitter from Facebook, where he spent the past four years. He will be the new director of sales for the Eastern (U.S.) region. Meanwhile, Amanda Levy is joining Twitter from Yelp, where she spent the past five years. She'll be the new director of sales for the West (U.S.) region.
