Duct Tape Marketing continues its discussion of community with the post, Contests Create Community. It points out how two organizations, the Washington D.C. Metro System and MasterCard, have asked customers to become involved with their services and promotions via contests. I was thrilled to see these companies inviting customers to be a part of their services and in such a fun way. Heck, if the D.C. Metro System can do it, so can we (and numerous libraries already have!).
