I found the phrase “old hat” in the following sentence of The New York Times’ article (April 20) titled, “The Tech-Savvy Traveler.”
AT 28 years old, Soraya Darabi is an old hat at staying on the cutting edge of social media. Her first job out of college was in the communications department for Condé Nast Digital for products like epicurious.com. At 23, she became the manager of digital partnerships and social media at The New York Times and went on to help found Foodspotting (foodspotting.com), a Web site and digital application that aggregates real-time dining advice.
What did the journalist mean when she wrote "an old hat"?
