Of course, it has nothing to do with people's 'rights' (or lack thereof) to libel, it has everything to do with who's responsible. Demon Internet estimates that there are one million individual articles posted every day on their servers. My experience on the internet says this is a reasonable number. If this is not overturned, then ISPs are going to be forced to essentially shut down the Usenet, the Web, and basically, anything where their users can send out.
