Well, following in the footsteps of the larger blogs, I'm going to have to disable trackbacks on all past and future posts. The signal-to-noise ratio is simply too low for them to be worth it. Almost all of my recent trackbacks have come from Murdoc's weekly Linkzookery, and as much as I appreciate them they aren't worth the ~1000 spam trackbacks I have to delete every week. So, the trackbacks are going away. Too bad, they were a neat invention... but with all the blog connection tracking sites that are around these days it's easy to find who is linking to you by other means.
Thanks again, spammers.
