Super Bowl XLIII is nearly upon us, multimillion dollar ads in tow, and since there’s never been as much video, connectivity or interactivity as there is right now, the whole thing is shaping up to be quite the Web 2.0 extravaganza.

From YouTube to Twitter to Facebook and beyond, here’s your guide to all the digital venues available to view, vote on and even interact with in this year’s lineup of ad campaigns.

There is no shortage of sites on which to watch (and rewatch, again and again) the ads: NBC, the game’s official broadcaster, Spike, YouTube, and Hulu, to name just a few (see below for a list). Many of these sites have already aggregated a number of previews and will allow you to vote for your favorite commercials or rank them.

Speaking of Hulu, the video site has created a customizable Super Bowl ad widget that will allow you to display and vote on the ads and can be embedded into Web sites or blogs. The Hulu folks have also been spreading some talk about how they will “reveal the secret behind Hulu” during Super Bowl Sunday. Really, Hulu? We are sweating in anticipation (not).

Many of the companies whose ads will be featured during the game also have content on their corporate Web sites. Some–like the Orlando Sentinel–are playing coy, releasing only teaser clips about their actual ad–essentially creating a commercial about a commercial. It has something to do with a kid in a cape, accompanied by some very somber background piano music.

Others have already released full versions of their ads online. Internet domain company Go Daddy has put two titillating ads up on its site starring sexy race car driver Danica Patrick, fresh from her big debut last year. The company will also feature Internet-only ads with a more salacious spin on the made-for-TV ones.

Meanwhile, sites like Spotbowl and Superbowl-Ads have aggregated lots of information about the commercials. Spotbowl has collected industry rumors and reports and boasts a fairly detailed list of all of this year’s ad sponsors, noting the type of commercial(s) each will play and behind-the-scenes information on many of them.

Superbowl-Ads presents perhaps the most complete Web 2.0 package, which will not only feature the commercials online, but has established a Facebook and Twitter presence as well. Its Facebook site features much of the same content as the site, but also has a video viewer, news tracker apps and discussion board.

And you can even befriend the famous Etrade Baby, who will make another appearance this year. Find him on Twitter under “etradebaby,” although he hasn’t had much to say so far. At the time of this writing, his most recent, and rather cryptic, message was, “I have very little time or patience for clowns.”

You can also follow Superbowl-Ads on Twitter under “superbowlad,” or search #superads09 and #sb43ads for a constant stream of relevant links, information and chatter leading up to and going into the big game.

Meanwhile, Forrester analyst Jeremiah Owyang will be conducting a “TwitterBowl” experiment during the game whereby you can send in your votes to @superbowlads (with an “s” at the end), commenting on the ads and giving each a rating of up to five stars.

Even iTunes is in on the party this year, as you’ll be able to download original music from Pepsi’s SoBe Lifewater ad. Said commercial is one of the few that will be shown in 3-D, provided that you’ve picked up your new 3-D glasses, since the old red-and-blues won’t do the trick, apparently.

So digitally speaking, you’re all ready for the big game. That is, unless, you were looking for actual information about that big game, in which case you’d probably do better somewhere else.

Digital Daily was on hand at Macworld ’09 Monday. Despite the flurry of wonky reporting about the health and/or “imminent death” of Steve Jobs–put into perspective here by BoomTown–nothing too remarkable happened during Apple’s (AAPL) final appearance at the annual event. Phil Schiller did a solid job delivering the keynote in Jobs’s place, introducing a new 17-inch MacBook Pro with an eight-hour internal battery and some innovative updates to iWork and iLife. Schiller ended his keynote with the announcement of changes in pricing and digital rights management for iTunes, punctuated by the surprise appearance of crooner Tony Bennett. Apparently, as Bennett sang, the best is yet to come. Crack photojournalist Adam Tow was on hand to capture the keynote in its entirety–All Things Digital’s photo coverage can be found here.

MediaMemo reported from CES about the pervasive 3-D theme of the conference and wondered whether people would pay cash to see a football game in 3-D at a theater instead of just staying home. There was the ongoing litany of the casualties of the econalypse: “Semantic” ad network Peer39 shut down its ad operation this week, Hearst is about to pull the plug on the Seattle Post-Intelligencer, Forbes announced layoffs and Sir Howard Stringer announced the elimination of thousands of jobs at Sony (SNE). MediaMemo also caught the much anticipated introduction of Palm’s (PALM) new smartphone, the Palm Pre, and its new Web OS, a combo Palm deems superior to the iPhone and that many others consider Palm’s last chance for survival. The product’s success or failure will have a lot to do with its pricing, about which there’s much disbelief.

BoomTown had the lowdown this week on an amusing rumor about a Microsoft-backed (MSFT) run at Yahoo (YHOO), the emergence of Carol Bartz as the top prospect for Yahoo CEO and Microsoft’s deal with Verizon (VZ) and Dell (DELL) to distribute search. Jerry Yang submitted to the all-seeing eye of BoomTown’s Flip camera along with Yahoo President Sue Decker to talk about Yahoo’s new product, Connected TV. The camera also caught some chatty attendees and a few demos, including one of a new Disney (DIS) music product given by a guy who looked like a member of ZZ Top.

Speaking of ZZ Top, catch gadget godfather Walt Mossberg trying out some 3-D glasses on his annual odyssey around the convention floor. All he needs is a longer beard and a ‘32 Ford and he could be a band member, too. Walt and colleague Katie Boehret caught many of the more interesting gadgets on video, and Walt previewed some more for FOX News.

More next week.
