CEO, COO, CIO, CFO -- all TLAs that most folks would be proud to see blooming on their business cards. Get ready for a new one. It's CDO, Chief Digital Officer, a position recently created in New York City and now occupied by one Rachel Sterne. She's something of a social media maven and is the founder of GroundReport, an aggregator of user-created news stories. She'll now be tasked with improving the city's ability to leverage social networks and the internet as a whole to communicate with its residents. We're not sure if this will actually entail the digitization of Rachel herself, but we're wondering if maybe that's already been taken care of. See for yourself after the break.
