Journalist David Tebbutt links from his blog to an article he wrote for Information World Review entitled Genie in a Bottle. In it, he explores the deep fear that some companies have about introducing social computing into their operations. As Al Tepper, head of online development at Caspian Publishing points out in the piece, some companies have quite valid reasons to be scared - and they should be. In his words, "if you’ve got something to hide, you’ve got something to fear." As Tebbutt concludes:

This is bad news indeed for those who maintain their position through manipulation, hoarding information or playing politics.

In which case, you have bigger, more fundamental issues to worry about than social media.
