I don't think you can call that "leaked"—it was an interview with PG!
Also, the orange name thing had been discussed on HN long before then. More than once, IIRC. (Sorry, I don't have citations—too tired to dig them up.)

Thanks for the clarification! I agree, leaked was not a proper way of describing it.
