Earlier this week, the “Wal-Marting Across America” blog – ostensibly the musings of a happy couple traveling the country in an RV while overnighting only in Wal-Mart parking lots – was outed for being bankrolled by Wal-Mart’s outside PR firm, Edelman. This is not the first time Wal-Mart has been caught pushing the ethical boundaries of the blogosphere. Granted, the retail giant desperately needs some ammo for its ongoing steel-cage death match against its well-organized critics, but come on – what was it possibly thinking? I continue to be amazed when big brands and their big agencies swing and miss so badly. Wal-Mart got its buzz alright, but once again for all the wrong reasons.
