Glenn Kelman, chief executive of the online discount real estate brokerage Redfin Corp., said he went too far with a blog entry last June. He posted the name and photo of a real estate agent who he claimed refused to work with Redfin under the heading “The Hall of Shame.”

In an interview in the Puget Sound Business Journal 1/26/07, Kelman admits it unduly antagonized the real estate industry. In retrospect, “I wish I’d been more diplomatic.”

To Kelman’s credit, he hasn’t deleted the post. Couldn’t anyway, really, as it will exist in perpetuity online.

As the article notes:

But many CEOs are finding that the desire for transparency and accessibility isn’t always compatible with an executive role. Indeed, just as employees have learned the cost of posting too-personal details on MySpace, CEOs are discovering that chatting in cyberspace can backfire — sometimes disastrously.

What can one do if they write something they later regret? Is there anyway to expunge the post?

Some companies, such as Reputation Defender, have sprung up claiming to be able to erase your online presence. They claim to scour the Internet to dig up every possible piece of information about you, allowing you to select the unwanted info. Then “Our trained and expert online reputation advocates use an array of proprietary techniques developed in-house to correct and/or completely remove the selected unwanted content from the web.” The charge for this service? $29.99 per nasty item. “When we find an item of online content you don’t like, we’ll carry out our proprietary DESTROY process for you on that item. This is where the rubber hits the road. It is an arduous and time-consuming process for our team of specialists, but we work hard so you can sleep better at night.”

Of course, by using a service like this, it could backfire and you could end up looking even more foolish.
