Today, we debut our new redesign of the home screen of AllThingsD.com.

It is, in fact, our second redesign since we launched the site in late April of 2007, although it is a much more drastic redesign, with a lot more elements added.

Why did we do it? No, we are not hyperactive (OK, we are, but we are taking medication for that).

Actually, it is because we in the ATD brain trust (that would be Walt Mossberg and me), along with our many much-more-intelligent staffers and advisers, wanted to bring even more digital news and analysis to our readers by making more stories available on the front page from us and also from around the Web.

Our aim was simple: Now newsier than ever!

In fact, we hope you will find our new look linktastic, as we try hard to embrace the notion that ATD’s audience wants to be able to find great tech and media stories anywhere and everywhere.

Just fyi, the inside sections remain exactly the same–it is only the front page that has undergone the renovation.

Here’s a quick tour, from the top to the bottom of the page:

Megablog: We combined the BoomTown and John Paczkowski’s Digital Daily blogs in one rolling one in the center rail.

We felt that it allowed us to feature a lot more of our stories on the main page longer, up to 20 typically, and also made it easier for readers to find stories before they dropped off the front.

We will be adding more material to this section soon, as we develop our content further.

Walt Mossberg: Walt’s weekly Personal Technology and Mailbox columns and Mossblog, as well as Katherine Boehret’s Mossberg Solution, move up and to the right in a high-profile spot.

As ever, Walt is the site’s amazing anchor and a tech consumer’s greatest adviser, telling it like it is and writing reviews that matter.

Tech Headlines: On the top left, we wanted to bring in the stellar work from our Dow Jones brethren at The Wall Street Journal, Barron’s and MarketWatch, as well as from the Dow Jones newswires, to give readers links to as many stories as we can as news breaks.

This section will be updated every nine minutes to keep it fresh and new.

Voices: This section on the left remains the same, except it goes vertical. We try to hand-select (no stinkin’ algorithm for us) from across the digital blogosphere, so we can feature blog posts we think you need to see to keep up.

Also, expect more guest bloggers who write original posts just for ATD, like one tomorrow from Slide’s Keith Rabois, giving BoomTown a hard time for our problem with juvenile widgets.

The Tech Top 10: Also on the left, just below Voices, we keep our edited Tech Top 10, a list of the stories we think you need to know about every day.

Video: On the right is our featured video. We do a lot of video at ATD and we will feature our latest-posted here.

Tech Around the Web: Also on the right, we are posting, via RSS, the feed from four digital news sources we like and think are useful for our audience.

Two are editorially driven sites, paidContent and GigaOm, who we believe are combining the energy of the blogosphere and also providing readers with trusted reporting that also adheres to the standards of accuracy and ethics we try to operate under too.

This is a big focus for us at ATD and we want to point readers to high-quality material. They say you are judged by the company you keep and we could not agree more.

Both Digg and Techmeme, of course, are the key news aggregators of the sector and we like how helpful they are in surfacing important tech and media stories for readers.

Just click on each tab to get to each section. This section will also be constantly refreshed throughout the day.

More ads: Well, we have to pay the bills, don’t we? We hope you do find them useful and don’t find them too intrusive.

There will be even more to come from us in the coming weeks, especially as we gear up for the sixth edition of the D: All Things Digital conference, which is taking place May 27 to 29.

So, please let us know what you think of our new look, as we would love feedback.

And special thanks to all who worked on the redesign, including Mike Monteiro of Mule Design Studio and especially the tireless and multi-talented Adam Tow, our Web genius.

Because this is the fast-moving Web and we are a bunch of hip, hopping hep cats, we’re doing some renovation to the AllThingsD.com site and also turbocharging the Voices section too.

The site is still powered by those lovely folks over at WordPress and keeps the amazing style created by the truly intelligent designers over at San Francisco’s Mule Design Studio. And it is still all free, all the time.

But, on Monday, as if by magic–the magic of our Web genius Adam Tow, that is–we will have moved the digital furniture around on our front page, adding our occasional Tech Top 10 every day by our own John Sullivan and also a featured daily video.

And we will be rearranging all the pieces–BoomTown, John Paczkowski’s Digital Daily, Walt Mossberg‘s many columns (including Katherine Boehret’s Mossberg Solution) and Voices–to make it prettier and easier to use, in our ongoing attempts to give readers more, more, more.

And who doesn’t want more? Those grumpy folks who are never satisfied, that’s who (and you know who you are and so does BoomTown and how we wish you would just learn to live, live, live and join our noisy circus, which is what you know you want to do)!

We think even the glummest of the glum will like our new iteration of our Voices section–which we have admittedly not paid enough attention to since our spring launch. All that will change, as we try to provide you with new viewpoints from important players around the Internet every day.

Culling from the mountains of content from the Internet, we’ll be pointing to lots of tech and media posts, videos, graphs and cartoons from the most interesting and reliable sources to bring you information you need to know about.

No soulless algorithms here–we’ll try to choose the best stuff for our readers, to give them what they need to be fully informed, all with the kind of taste and high standards all Dow Jones properties aim for.

Plus, we will be soliciting and publishing more quality original blogs too–in text and video–from the top echelons of the digital industry, trying to bring the same sort of high-level debate and insights that we present annually at the D: All Things Digital conference.

What else? Well, we’ll be adding more information about our crack D and ATD staffs on the About Us pages.

And we’ll be bringing you extensive and sassy coverage by our team in 2008 from exciting upcoming tech and media industry events like the Consumer Electronics Show, MacWorld and Sundance, to name a few.

Of course, there is more stuff to come soon, but we’ll keep it to ourselves, as we don’t want this exciting news to turn into Geeks Gone Wild.

Well, maybe just a little bit–here’s that great Maria Sharapova “I Feel Pretty” video for Nike that we so love and for which we thank the universe for providing to us via the miracle of the Internet:
