So why should you use Twitter? As with all social media networks, it is important for a digital leader to be visible on the digital tools that colleagues, employees and peers use. Consider Twitter an opportunity to build your personal brand, and in turn to develop a richer network of contacts. Twitter is also a good source of information on both people and industry. And, finally, it is a great place from which to promote your views and influence industry trends - but only if you do it right.
