I was also surprised that it does not work in IE9 - to make matters more annoying, the back button decided not to work (it just kept flashing me back to the 'We heart websockets' tagline. Lack of IE9 support is an irritant (one fixable with fallback, bout your business, your call). But that annoying back button issue that resulted in me having to close my browser and reload just to get back to HN to make this comment is on my short list of web behaviors that make me never wish to visit a site or vendor again. It does surprise me how many web sites, especially ones in many cases geared towards dev teams, either explicitly cut IE8/9 out of the picture, or render so horribly that they make me wonder whether they intentionally degrade the experience to be 'clever' or if they really just do not care about that much of their market share. For the record, I have the most current versions of IE, Chrome, and Firefox on my PC, and run Win7, Win8, Ubuntu and OSX on other PCs just to make sure my web properties are useable for 95%+ of my visitors (I've cut IE7 support recently, but IE8 is still about 20% of my traffic).
