What's that, non-Windows-7 users? You've never heard of the operating system's neat three-dimensional window organizer? Let's try it out together. Grab a copy of the operating system, do all that installation stuff, then hold down your Windows key and hit Tab when you're finally on your desktop. Presto - provided Aero's on, all of your open windows will shift out into a neat little three-dimensional display that you can quickly scroll through using your mouse wheel.
Of course, someone's made a Firefox addon to mimic this creative functionality. And while it might seem gimmicky at first glance, rest assured that you will be the coolest (and most organized) person on your block once you start showing off your brand-new way to keep tabs on your multiple browser... tabs.
If war movies, zombies hordes, or stormtroopers have taught us anything, it's that there's power to be had in numbers--well, maybe not the stormtroopers. Regardless, a number of Web apps take advantage of this philosophy to offer increased functionality, awesome services, or cheap deals for those who are part of a herd. Kickstarter, for example, allows groups of people to team up and pledge funding for a number of independent projects. If a project meets its funding goal, then everyone who pledge an amount has to pay. If not, nobody pays a dime.
But you don't want to pay money. No, you want to save money. Have no fear--there's a Web app that takes this altruistic function and spins it on its head. Instead of pledging to donate, you're pledging to buy at group-discount prices!
