Social networking is a big part of what makes extension successful. I think most program teams will tell you that and I know that is the case in most of my experiences 'selling' a program. It is always helpful to "know" the right people in the community who will help promote a program to make it work. Whether they are part of a public agency, committee, private business, commissioner, health field, education, their marketing is critical. Our work hinges on the connnections we have to people. I don't see facebook or my space helping us in this realm. It is more personal/private in nature. But hey, I could be wrong.
