Now that I sort-of-understand TrackBack, James Cox introduces me (personally, at Garlic & Shots last night) to TrackForward:
So my proposal is a protocol to do a reverse - trackback: a TrackForward. (or PingForward). When I post, i can select or paste urls to TrackForward, notifying a person's aggregator/blog/email/im that i've posted something that i think they might be interested in.
