New York City has many tech hubs, but most revolve around the big money in downtown Manhattan. Now Harlem wants a piece of the action. There’s a new co-working space there called Harlem Garage. Marketplace Tech Report host Ben Johnson headed uptown recently to get a tour of the spot, which opens officially in a few days. Ben was shown around by Ryan Young, who works for MicroOffice, the company that manages the space, as well as Clayton Banks and Bruce Lincoln of Silicon Harlem.
