Twitter will open an office in downtown Detroit to better serve marketers and advertising agencies. Led by Greg Myrick, a sales executive hired from Yahoo, the Detroit office is the latest in a series of sales offices the company opened in the past year in cities, such as Washington, DC, Cincinnati, Austin and Atlanta, adding to Chicago, New York, Tokyo, London and Dublin. The handful of Twitter employees in the city will work from the M@dison Building, a co-working space located in a historic 100-year old building shared by several tech startups in the city.
