I did a quick search in this group for trackback and pingback but
didn't come across anything. As someone that uses del.icio.us to
write commentary on the resources that I bookmark, I thought it'd be
cool to send a trackback/pingback to them. Lots of the resources won't
accept trackbacks/pingbacks but if they're blog posts I'd expect them to.

Ahh, just realised that we would need to send a permalink of our
bookmark - something that I don't believe currently exists in
del.icio.us...

Any thoughts?
