You would be hard pressed to find someone with a more hectic and busy career than a meeting planner. The amount of detail they have to co-ordinate to put that meeting/conference/expo together is vast.
They have tons of email. They are constantly bombarded with prospecting cold calls. Busy is a word that doesn't even begin to describe them.
What does this have to do with LinkedIn? I'm in the USA right now, Chicago for a speaking engagement for the Americas Business Incentive Travel Meetings Conference and Expo. One of the sessions I attended was a panel of meeting planners discussing how suppliers can get through to them.
They said 'we are so busy we don't have time. We screen all incoming phone calls and don't respond to people we don't know. We have hundreds of emails so let prospecting ones slip by. Facebook is full of junk. So really the only place you can get through to us is on LinkedIn. We will pay attention to that because we can find out more about you easily and get references from colleagues of ours you work with'.
So it is not just me that likes and uses LinkedIn.
