The guru behind SEO Book Aaron Wall (who for the record is also advertising here with BlogAds) is being sued by Traffic-Power.com in relation to comments left on his blog by other people.
More details on Aarons blog here. Intuitive Systems also has more details. Robert Scoble, in a fit of insanity is suggesting that the solution is to moderate or turn off your comments. How bout free speech Scoble?
If successful the case has the potential to cause major upheaval in the blogosphere as comments would need to be filtered in cases where there was even the slightest chance someone might sue or find the comment offensive or disagree with it.
Mght be time to update the disclosure and editorial statement.
