Have you shoveled any of your consumers' driveways lately? Just about everyone but Newark, N.J. Mayor Cory Booker can put their hands down. Booker, savvy enough to get some positive ink for Newark, is not a bad role model for marketers. As Mashable reported yesterday, New Jersey radio show host Ravie Rave tweeted that her 65-year-old father needed help shoveling snow, and Booker promptly responded, saying he would "get 2 his Driveway by noon. I've got salt, shovels & great volunteers." The story went on to make headlines on CNN and elsewhere.
