Screaming Penguin - Source Does Matter

Well, and as I noted, we simply haven't hooked the java trackback server into the PHP penguin code, but that aside...

I think trackbacks or pingbacks are *good*. I think an active notification technology, vs a passive scan one is a good thing. My real point as to "good vs bad" is that the trackback notification system is better, while the pingback autodiscovery system is better. Frankly, given the number of people that fuck up (a) simple valid XML or (b) the whole RDF syntax in there Trackback autodiscovery is just... saaad. Pingbacks is much simpler, but it doesn't have an encoded document value like the RDF does.
