It's been a rough week for our ol' friends at Fox News. Thanks to some IP-address based research, the political world learned that the FNC was responsible for "touching up" Wikipedia pages, editing content that didn't fit with the partisan network's political agenda.

For example, embarrassing content from Media Matters about FNC personalities was quietly removed. Criticism of Keith Olbermann and Al Franken was accentuated. The network that specializes in on-air propaganda had taken its usual schtick to Wiki pages.

With that in mind, it shouldn't surprise anyone that Fox News' Chris Wallace -- you guessed it -- sought to undermine Wikipedia's credibility with a report tonight.

The irony is rich. Pay particular attention to the references to "self-serving agendas" and businesses desperate to "improve their public image."

Fox News tried to exploit Wikipedia, and got caught, so naturally it's time to undermine the source of the network's embarrassment. Typical.
