Why is this important? Well, it's importance depends on it's popularity, but it frees comments from websites by opening all websites to comments--outside any comment, moderation or policy of a site.
People can have discussions around your site, rather than on it. Google wins by collecting information about pages and sites from humans rather than machines to grow their search algorithms. It's also another potential ad space--imagine an ad for Coke on the Pepsi homepage, Or ads from private sector employers in the same browser window as usajobs.gov.
For site owners, Google lets you claim your sites on Sidewiki. It's a good idea, too, since site owner comments appear first. You'll need a Google Webmaster Tools account.

It took my team about ten minutes.

This computing calamity allows Sidekick owners only a faint hope of backing up the information currently on their devices, and none of recovering anything they'd trusted to online storage. And it leaves T-Mobile and the operator of the Sidekick's data service, a Microsoft subsidiary formerly known as Danger, Inc. -- oh, the irony! -- with some serious explaining to do.--Read more on WaPost.
For government, at the simplest it means to make sure you know what you are buying, understand redundancies and risks, and NEVER let your data get out of your control. A tough reminder, caveat emptor.
