If I were a director or chairman type person in a big organisation or company, I would have people going on forums or facebook type services , asking questions, answering questions etc etc you need to keep upto date on current trends and make sure your company or organisation isnt losing touch with reality, if you doing something wrong you need to know about it so you can put it right an vice versa, also if you gonna bring something new out you need feedback and other peoples input who are not too close to the project or whos work its going to have inpact on.
Ideally a member from the CITB, HSE, NASC, MCG and others should be looking at what is being discussed on here and providing questions and answers on certain topics, obviously not all threads haha but threads that are related to their organisation, cisrs, unions the list goes on.
