> You're recreating Pingback in Trackback. ;)

In a way, you're right; it's arguably the best feature of Pingback.
Unfortunately, PB doesn't let Alice specify the text she wants to put
on Bob's blog, limiting its usefulness for leaving coherent comments.
That's one of the nice things about the Trackback idea (i.e., it's a
little more than just a link) but without link checking it's
fundamentally open to abuse.

Thanks!
