Trackback is a Go
I decided to go with "Followups" after reading what Edward Felten had to say about it.
I also hacked the CSS for the trackbacks page to make it easier to read and eliminated the stupid "new window" link (I hate those). Finally, I made the URL to ping my site for trackbacks is a link to make it easier to copy and paste.
Now I just need to get libwww-perl installed and I can send TrackBacks, too.
Happily, all of this is free software.
