InfoWorld — In the game of technological one-upmanship, the browser used to be an easy place to win. Most people used Internet Explorer, so it was simple to gain the edge by using Firefox. But now Firefox is common, and even Opera and Google Chrome are losing their cachet. Safari ships standard with every Mac, so everyone, the cool and the uncool, have it by default. They're all excellent browsers, but they're still the status quo. Is there anywhere else to turn for a bit of distinction?

Finding an even more obscure browser is surprisingly straightforward, and it may offer more than just the feeling of superiority that comes from beating the crowds.

There's some truth to this, but not always -- some of the unique capabilities can only be done deep inside the software. In any case, the job of parsing the terms and creating an exact definition of the Web browser isn't as much fun as embracing the idea that there are dozens of alternatives.

So here's a list of 10 browsers that are not Firefox, Chrome, Opera, Safari, or IE, but that are all the more useful because they're not. They aren't different because they have a different name and some buttons in other spots, but because they offer something that can't be found in the traditional browsers: a more useful representation of Web pages or search results, integration with social networking sites or other services, a lower resource footprint, faster page rendering, or even easy scriptability.
