Spam and porn are no longer an irritant on the net. They are changing the nature of the Internet from e-mail to blogs. They threaten to erode the fundamental glue of the Web – the link. If you link to an e-mail address or to a Web site that allows automated content through forms you threaten to destroy the end-points of your links. This blog has had not porn comments or junk links because it is unlinked – but if I provide links as a friend did on his blog, I run the risk of getting the wrong sorts of comments. So, the end of comments.
In short sporn swamps open dialogue on the net. It’s a fundamental pattern on the net – something like: if you are open to discussion you will be swamped by sporn.
