Carl Bialik from the WSJ writes "In a legal case being watched closely by bloggers, an Internet company has sued the owner of a blog for comments posted to his site by readers, the Wall Street Journal Online reports. Traffic-Power.com, which sells tools for boosting Web traffic, sued Aaron Wall, age 25, over statements posted in the comments section of Wall's search-engine-optimization blog, SEOBook.com. (Wall also has posted about the case.) 'Legal analysts said the case falls into somewhat murky legal territory, but that Mr. Wall may have some protection from liability under federal law,' WSJ.com says. 'Courts generally have held that the operators of computer message boards and mailing lists cannot be held liable for statements posted by other people. Blogs might be viewed in a similar light, they said.' However, Daniel Perry, a lawyer who has followed the case, says that Wall's case is complicated by his own negative comments about Traffic-Power, which could be seen as a competitor to his site. 'To be candid, he sort of moved into this moving propeller,' Perry said. 'The Internet is not your personal stump to beat up people.'"
