Bloggers Gain Libel Protection - Xeni Jardin, Wired


The Ninth Circuit Court of Appeals ruled last Tuesday that Web loggers,
website operators and e-mail list editors can't be held responsible for
libel for information they republish, extending crucial First Amendment
protections to do-it-yourself online publishers. Online free speech
advocates praised the decision as a victory. The ruling effectively
differentiates conventional news media, which can be sued relatively
easily for libel, from certain forms of online communication such as
moderated e-mail lists. One implication is that DIY publishers like
bloggers cannot be sued as easily.
