NEW YORK ( TheStreet) - When I was in journalism school, 35 years ago, we talked a lot about credibility. Credibility is something you build brick by brick, day by day. But it can all come tumbling down with a single mistake. I've seen that throughout my career. An attention deficit can be a huge burden to a journalist, because although I may have written more interesting copy than my co-workers, I also made mistakes. I paid for them with my jobs, and lost my credibility. Which I then proceeded to build back, brick by brick and day by day. In the age of social media, we're all journalists. And we all have credibility accounts that can be quickly depleted, based not just on our actions but on how we react to things. When we screw up, it's better to take the hit than to deny the stupid things we do. UAL - Get Report) United Airlines faced a test of credibility last week. For 15 minutes, it accidentally gave away some tickets booked at its Web site. Purchasers paid only the 9/11 security fee, totaling $5 or $10. The airline decided, after some consideration, to honor the tickets. The result was stories such as this one, on a Patch site near the company's Chicago headquarters. It was about a family getting a Disneyland vacation for just $60. The goodwill from stories like that, United concluded, was worth the financial hit. The Bureau of Transportation Statistics estimates there are 643 million passengers booked each year on U.S. airlines. That's about 1.76 million per day. Given United's 15.8% market share, we can figure it got about 278,000 of them.
That's the business point here. We're all in full view of everyone, every day.

Relatively transparent pricing, a sense of humor about things -- let's get through these few uncomfortable hours together and everything will be all right. It works more often than it doesn't. Companies, and countries, aren't accustomed to making these kinds of calculations. Obviously, neither are some politicians. Nor high school districts. But it's just this kind of calculation you have to make in a socially connected age. What I was taught, back in the 1970s, was that I should live as though my every move was on TV, and this has been good advice. When I screw up I tend to admit it, and I take my medicine, no matter how bitter that might be. We're all journalists now. Whether we're private citizens or public companies, we all have our credibility accounts, and we need to nurture those accounts by being as good as our word, confessing our errors, and making ourselves appear worthy of trust.
