SOME GOOD NEWS AND SOME BAD NEWS
The good news is that the Ninth Circuit Court of Appeals has ruled that bloggers can't be held responsible for libel for information they republish, extending crucial First Amendment protections to do-it-yourself online publishers.
Bad news is that SPAM IS GETTING SMARTER! From the article: In an experiment last year, US researchers at the Center for Democracy and Technology created 250 email addresses, some of which were posted in the public domain and others in the corporate domain. Some addresses were posted using the A symbol, while others used human-readable equivalents: "fredAbloggster.com" would be written "fred at bloggster dot com". During their six-month study, the team received around 10,000 emails, 8,400 of which were spam.
Any way you slice it, it ain't getting better.
