Maybe it's just my warped mind, but one of the first things I wondered was whether Google Instant Previews would from instantly appearing, as it did with the original Google Instant feature. Google's for the blacklisting made enough sense, by the way: You can always search for that stuff by hitting the "enter" key -- but having the material pop up automatically could cause a child to be inadvertently exposed to something saucy.

Strictly in the name of research, then, I took it upon myself to search for a few terms far too raunchy to spell out here. (Hey, it's a tough job, but someone's gotta do it.) The verdict: Google does not block adult-oriented content from showing up in its Instant Previews feature. In other words, depending upon what your search entails, click the magnifying glass with caution; whatever's on the sites will show up in the previews on your screen.

In general, I found Google Instant Previews to be a fairly handy feature. While the original Google Instant option did little more than annoy me (I disabled that bad boy about 5 minutes after it came online), I could see this one being something I'd actually use. Google suggests using it for times when you want to compare results, find a result that meets a specific need -- something with a chart or image, for example -- or quickly find a page you'd previously visited without having to click through to a dozen different sites. I could envision myself using it in any of those contexts.

So there's your tour -- now, ready to try out Google Instant Previews for yourself? Head to to give it a whirl. If the page doesn't load for you, don't worry: Google says the feature is being rolled out as we speak and will be available to everyone soon.
