The Wall St. Journal and some other publications are reporting on an interesting story about a blogger, Aaron Wall, being sued for comments made on his blog, SEOBook.com. Apparently, some of Wall's readers had unkind things to say about Traffic-Power.com. In response, Traffic-Power decided to file a lawsuit in a Nevada court, which lists several unnamed users of the blog. The WSJ said Wall could have some legal protection because the courts have ruled in the past that people who run computer message boards and mailing lists can't be held liable for comments posted by other people. It's an intriguing issue given there are so many blogs out there and most comments are made by anonymous users. But until this case is addressed by the courts, it's difficult to say whether bloggers should be worried.
