You're absolutely right that when it comes to creating exhibitions and events, it is absolutely vital to judge what our visitor response has been. We actually do incorporate a number of different methods to judge visitor satisfaction, the most important of which is simply surveying people immediately after their visit or the event. We have a screening program in which we provide cards, basically, for people to fill out with regard to their satisfaction. We also do customer surveys that involve having members of staff ask people questions. As well, we do bring in external organizations, such as the University of Toronto and a group called the G6 within Toronto, which is a group of museums that collectively look at marketing and visitor statistics. They bring in their own surveyors.
I'd say there are probably at least five or six different methods of surveying our visitors to find out whether their experience or the content was what they were looking for.
