It is necessary in older non-syncro crash boxes to blip the throttle in neutral. Today in a modern car, it's not needed, nor will it trash a gear box, it may be easier on the syncros, but it's not necessary...nor is it a recipe for quick/smooth shifts...

I'm not recommending double clutching, my method uses the clutch just once, just blip as you are going through neutral. Its no slower than putting it in the lower gear first, then blipping, it actually faster, you are doing two things at once, blipping the throttle and moving the gear shift.
And blipping while going through neutral does save a modern synchro mesh tranny. Even with the clutch depressed, there is some drag in the clutch and blipping the throttle while in neutral will spin up the input shaft some, which means the synchro has to do less work.
