Because we don't need yet another domain to host a .js file or a nifty way of displaying something. HN is polluted with "Look guys, I made a jQuery plugin over the weekend, so instead of linking my Github you can check it here yetanotheruselessdomain.io". I might be bitter though, since whenever I want to register a domain for a genuine product/service it is usually taken with a "Buy this domain" link on it and nothing else. Too many domains are being used for silly purposes while taking them off the market from those that could give them much bigger potential.
