I have been asking many of the event coordinators I know how they gather feedback from their attendees. With all of the social media tools that we have that allow us to listen in online to conversations that others are having, we get a chance to hear first hand what many are saying. We can see what they say on Twitter during the show and we can see what they say on their Facebook pages after they get home and finally blogs are a great source for reviews of how your event went or how the show was perceived by those in attendance.
Listening to that feedback can be invaluable when you are wanting to implement changes to your format, your exhibit space or other parts of a show to make sure you are keeping the sponsors happy, the attendees and the exhibitors. I was reading recently that a convention that was taking place in Las Vegas is now moving due to the feedback received by the attendees. This is a bit of a drastic move on the part of the organizers but it may provide to be the best move for their business. They listened to what was being said about the location and now are moving from Las Vegas to Anaheim. Listening to your detractors is hard but you can make it a positive.
