[Selected quotes from above]
"For the first time, the case has brought into sharp focus the potential
for an Internet service provider to be liable globally for defamatory
material published through its services."
"His reading of the law was that liability could be established if the
material was proven to be defamatory; if the service provider knew
the material was being published; and if no action was taken to stop
it."
