For instance, I'm a big fan of roller coasters. In the past I've used Google to search for information about roller coasters, such as which ones are the tallest, fastest, and have the most loops. Finding this information used to take multiple searches — I'd find roller coaster sizes on one website, heights on another, and speeds on a third. By manually comparing the sites, I could get the information I was looking for, but it took some time. With Google Squared, a new feature just released in Google Labs, I can find my roller coaster facts almost instantly.

Here's how it works: In Google Wave you create a wave and add people to it. Everyone on your wave can use richly formatted text, photos, gadgets, and even feeds from other sources on the web. They can insert a reply or edit the wave directly. It's concurrent rich-text editing, where you see on your screen nearly instantly what your fellow collaborators are typing in your wave. That means Google Wave is just as well suited for quick messages as for persistent content — it allows for both collaboration and communication. You can also use "playback" to rewind the wave and see how it evolved.
