It's worse than I had originally thought… My weblog was (I hope it is no longer) bringing down Safari. – and then reports of this (I'm quoting here from a remarkably calm Dave Ely):
It's not just your site, butt also your feed which locks up WebKit (killing NetNewsWire). I suspect that it's something in the LDAP spec table down stream a bit.
Not my feed too! It can't be!
I don't yet know what NetNewsWire is (though it sounds really, really important), but RadioLand technical support said that although they could see nothing wrong with my blog, I should probably simplify my LDAP spec table – which, I must admit, went through several magical translations (all automated). Are the fates punishing me for my work on mapping? No, that can't be.
