I don't think "It's really good" is appropriate for this title. It's pretty cool, but its no more than a site with some javascript examples. It's not really good if you are trying to learn about game development as no links are like "START HERE" or "Tutorial" its more of a reference for people that already make games.
this site seems like a bandaid for the IE problem drawing attention to what IE can do rather than what it cannot.
Looks reasonable. IE 10 could be better, but you know, it's great that we'll soon be seeing lots of Windows 8 computers with support for these web standards.
