Spellchecker, fixed.

The Uncredible Hallq, I thought Feynman's intro to SR in the Lectures was perfectly okay. And I think John Baez has up an intro to GR.

But mostly, I haven't seen textbooks botching the explanation, because relativity is not something that you are supposed to be or allowed to be confused by, and so there is no excuse for confusing students. And because no one is "interpreting" the equations, of course. Three cheers for physical realism!
