Btw...
I spent a couple of enjoyable hours cruising Bad Astronomy's PX files this morning, as well as the "Planet X and the Pole Shift" site Plait links to quite ofen during his exposition, just so I could catch up on all the hoo-hah and get a few chuckles. [I read Worlds in Collision 35 years ago, while still in high school, and already knew enough celestial mechanics to laugh out loud.]
Anyone else notice that every link to ZetaTalk returns a "Cannot find Server" error? Has she pulled the plug and run to the hills already?
