Just an FYI, I've started moderating my trackbacks to stem the tide of spam (ew…tide of spam…horrible image. Sorry.). So, don't worry if your trackback doesn't appear right away — it's just waiting for my approval, which I generally provide within hours. Unless you're an evil spammer, in which case I dispose of you. Bwaa ha ha ha!
If you're not sure what trackback is or how to use it, let me know.
