Somebody at the CIA tweaked Oprah's Wikipedia entry

The BBC reports that Wikipedia Scanner, a tool that can identify the source of edits to Wikipedia pages, revealed that workers from CIA computers have altered a number of Wikipedia entries. So what insightful additions did the Agency allegedly contribute?

On the profile of Iranian President Mahmoud Ahmadinejad, the tool indicates that a worker on the CIA network reportedly added the exclamation "Wahhhhhh!" before a section on the leader's plans for his presidency.

A warning on the profile of the anonymous editor reads: "You have recently vandalised a Wikipedia article, and you are now being asked to stop this type of behaviour."

The entries for Porter Goss, former CIA director, and Oprah Winfrey were also apparently edited by the CIA network user, though these changes were "more innocuous."
