CNN last year posted a list of 2006’s dumbest business blunders.

Of note is number 4, GM’s make your own commercial contest as part of their Apprentice promotion in which participants created commercials with slogans such as: “Yesterday’s technology today” and “Global warming isn’t a pretty SUV ad – it’s a frightening reality.” While a good idea, on paper, online communities have a habit of revealing your faults if you give them the chance.

Other interesting moments are number 10, Comcast repairman falls asleep waiting for customer support…the owner of the house made a video…

Long story short, when your customers have complaints, it pays to listen. They probably have a point…and eventually these things come back to bite you in the ass.
