From Roland Tanglao (just to prove I'm not the only person saying this): trackback is dead. "Trackback is broken, and I concur. It was broken right from the start, but we didn't know it because it seemed to work, or at least, work the way most people thought it should work." I don't know whether PubSub will be the long-term answer, but something like it will be: the principle is that you search (where you want, when you want) for sites linking to you, rather than depending on them to tell you (with dubious honesty) that they are linking to you.
