Ian Hickson has been going on for a while about Pingback. The spec says there are six known implementations; one of these is a server for Movable Type by Stuart Langridge, but I defy anyone to find it on his site. If it’s only for private use, I don’t mind, but in that case why advertise it… and if it’s already written, what does this mean?
(If it sounds like I want something for nothing… well, I guess I do, although I’ll provide whatever I can in return in the form of bug reports, patches, etc. As a friend’s e-mail signature says, humans are tool users, and I’m nothing if not human.)
Not that it matters, of course–trackbacks and pingbacks are just a big popularity contest anyway, right?
