It is generally acknowledged that ‘engagement’ is a good thing. It is better, at every level if your message (whatever form that takes) is not only ‘seen’ (whatever that means) by a large number of people, but that a good number of those people choose to do something that approximates to actually reading it, hearing it or viewing it and furthermore that they indicate that they have done so in some way or other.
The problem with the notion of engagement is that there are almost as many definitions as there are conferences on the subject.
