"The article discusses weblogs that attack companies with libel but whose authors are unidentifiable. Weblogs started as a simple way for people to keep online diaries.

The online haters have formidable allies amplifying their tirades to a potential worldwide audience of 900 million: Google, Yahoo and Microsoft, plus a raft of other weblog hosts.

The combination of massive reach and legal invulnerability makes corporate character assassination easy to carry out."
