One thing very few people seem to notice is that this bill doesn't just jeopardise online services with it's broad language, it jeopardises users who are not the source of the targeted content. Why? Because they too lose the CDA safe harbor, and it's easy to look at the way modern information services look (especially, e.g., social networking sites) and see ways that an enterprising lawyer might target third party users as “publishers” of, e.g., information that is visible to some other users because the targeted user interacted with the source in a particular way.
