What are we going to blame now? For years, the Firefox-Chrome crowd has painted Internet Explorer as the obstacle between us and the lush, luxuriant Web of the future. While those browsers supported next-generation coding tools like HTML5 that allowed for dazzling graphics, elegant games, and interactive tools, Microsoft's did not. (If you click on any of those previous three links in IE, you'll be disappointed.) If Internet Explorer doesn't support a browser-based tool or toy, it makes it a nonoption for any Web developer who wants a mass audience. By whichever measurement you use, Internet Explorer is the most popular browser around (61 percent of visitors to Slate, for example, use some version of IE).
