A couple days ago, Business Week published an update to a story it ran back in May 2005 about the impact of social media on business.  The update is presented as an annotated edition of the original article.  Changes are indicated by highlighted text, and the update information can be summoned by clicking on the information icon (that little circle with a lowercase "i" in it).  It's definitely interesting to see how things have changed and how predictions have panned out.

One of the more interesting updates touches on a point that is raised by businesses considering blogging.  They ask about the risks of letting their employees blog about company matters.  Here is what the update said:
Tim Bray, Sun's director of Web technologies, thinks we overstated the risks of company bloggers. He says that 4,000 bloggers at Sun, about 10% of the workforce, have had virtually no problems. And except for a few high-profile cases, like Mark Jen at Google, very few companies have had publicized problems with in-house bloggers. "I think there's a news story in the absence of carnage," he says. Jon Garfunkel responds on Blogspotting that a few punishments and firings could frighten in-house bloggers from "testing the limits"—and lead some of them to produce blog PR.
Compendium's software helps to manage this ever-so-small risk by providing administrative approval for both posts and comments.  You get blogging benefits without losing the control.
