Looks amazing! Really impressive results. Very cool that progressive loading is composed into the format. However I am afraid that without support from biggest companies the format will never gain popularity. Just think how long it took to make PNG a web standard. And animated PNGs? Died unnoticed. To make things worse, GIF, a stinking leftover from '90, is still in use (even on HN!).
