It is upsetting to know that Google and friends (Firefox, the open source people and the likes) are not continuing to support H.264, a common video codec widely used by Apple. As a user of H.264 (infrequently but still), I felt that it was a promising codec seeing how both Apple and Google supported it (Youtube was trying out a ton of H.264 vids if I'm not wrong). Still, there's no much hype about Web M which incidentally I only recalled upon reading the article above. At least Adobe is jumping onto the ship for Web M (a new open source codec project spearheaded by Google and joined by many many other platforms).
