Even using Akismet for anti-blog-spam (which seems to work pretty well), I’ve noticed that as far as trackbacks/pingbacks are concerned, I only get two types:

1. One of my own articles tracking back to itself for cross-referencing.
2. Spam that slips through Akismet.

So I’ve disabled trackbacks because they’re just a pain in my ass to moderate.  If anyone can provide a decent argument why I should re-enable them, I’m all ears.  Comment away.  (Comments are still enabled.)
