I think a real test in the courts would fail. Web sites are CREATED to give people access to their material. If anything, you are ASSISTING them and increasing their hits.
And as for the articles themselves, just do what FR does and excerpt them according to 'fair use' rules.
Basically you can't sue someone (and win) for using what you put out for public use.
Precisely. "Your Honor, this man damaged us irreparably by increasing our traffic. Why, I think he even caused a few people to register for our paid service! This damage cannot stand!!!"
