Shipbrokers are typically sociable animals but the social media world sets different challenges for communication.

At Maersk Broker chief executive Anders Hald has taken on the “Twitter Challenge” where he must communicate with staff and customers via social media – in 140 characters or less.

The trial began this month with Hald asked to answer: Who is Maersk Broker? It will continue in the coming months with the next due in August.
