So we are going to have ".mobi" domains soon, the idea being that these are meant for mobile devices. One one hand, I'm all about mobile. On another, sounds like a way for registrars to make more money. On another hand, is it so hard to detect the user agent on your server and direct them to a mobile version of your site? Haven't we had tools to do this for a while?
Next up, ".moz" sites for the anti-IE "look at our CSS implementation" crowd...
