Cnet discovers the virtues of Trackback spam:

"Jason Dowdell says that CNET News.com is being pelted by trackback spam and he wonders if any of the bloggers are actually generating any traffic from it. I have trackbacked CNET a few times and have seen nary a click through in my server logs. Perhaps it's because CNET doesn't list its trackbacks right underneath the news stories, but on separate pages that garner few visitors."
