The best thing about referrers is that they lead me to interesting places like the Abusable Technologies Awareness Center. This is a very serious effort run by a list of impressive, distinguished and serious people.
Just one thing: YOU GUYS NEED COMMENT SPAM CONTROL. MT-Blacklist works pretty well. You can find my (long!) list of banned sites at the URL for this blog with the filename blacklist and the suffix of txt after the dot. (Why no link? The file is behind a robot exclusion and I do not want search engines that might follow the link anyway to pick up all those terms and associate it with my blog.)
