Google hover website preview a great idea

Of course! When I first realized I was looking at a new feature - Google search website preview, it was obvious. The natural progression from Google's Instant search, and what a great idea. Now i can see how spammy and useless looking a link will be before I click it.

Update: Just found out this feature is called Instant Preview. Also, you can turn off Instant Previews by clicking the X in the top corner of the preview bubble. You can also turn off Instant Previews the same way you turn them on; by clicking the magnifying glass icon in any search result.
