I have no idea, nor do I know why Burda broke out into song either–how much do you have to love a media mogul willing to do that?

But I got it all on video and a whole lot more on the last day of the pre-Davos European gathering focused on digital issues and innovation.

(And here is a post by European serial entrepreneur Martin Varsavsky, who apparently thinks his video shows that Accel Partners’ Simon Levene and I were not impressed enough by Campbell.)

In any case, DLD’s motto was: “Uploading the 21st Century.” And while it did not quite do that, there were definitely a lot of interesting moments I captured for your viewing pleasure.

Along with Campbell (who was supposed to appear on a panel on Africa, but did not) and a singing Burda, the video features clips from two sessions today.

The first was titled “Exploding Media” and included: pundit Clay Shirky riffing on flash mobs; a very funny clip of kids talking about television (made by Technorati’s Peter Hirshberg); Google’s Marissa Mayer noting that Google will still not be in the content business; Yahoo’s Bradley Horowitz discussing Yahoo’s plans to de-focus on making original content; and BuzzMachine blogger Jeff Jarvis advising old media to just ask WWGD? (What would Google do?).

Another session on the video features the founders of the genetics-focused social-networking company 23andMe–Anne Wojcicki, Linda Avey and Esther Dyson–answering questions about fears people have about learning too much about DNA.

Here is the video (and now I am off to Hamburg to visit Xing, a business social-networking company):

I am now at the DLD conference in Munich, which is put on by Hubert Burda Media, a gathering that has become one of Europe’s most interesting in recent years.

The three-day DLD–which stands for Digital, Life, Design–focuses on digital innovation, science and culture and has the most cosmopolitan audience of any conference out there.

It is chaired by publisher Hubert Burda and serial Israeli investor Joseph Vardi and hosted by Stephanie Czerny and Marcel Reichart.

It is interesting to be here to garner a lot of different viewpoints from outside the U.S., and I will be visiting a lot of German Web start-ups over the next week.

There is also a lot of Olympic-level schmoozing, of course, since there are precious few such events in Europe compared to the conference-crazy U.S.

There are also, of course, a lot of the usual suspects from the States and especially Silicon Valley.

So far this morning, I have run into folks like former Microsoftie Linda Stone, Yahoo’s Bradley Horowitz, writer and entrepreneur Esther Dyson, Facebook’s Matt Cohler and, yes, Martha Stewart (who needs no introduction).

I am also here to interview onstage for DLD today Kenneth Roth (pictured here), longtime executive director of Human Rights Watch, which investigates, reports on and seeks to curb human-rights abuses in some 70 countries.

To say I am out of my league in interviewing such a serious and substantive figure is an understatement, especially given that I spend all my time contemplating the monetization of widgets (to be more specific, the non-monetization), the fate of content on the Web and the exact date the hype of social networking will end.

Still, I will give it my best effort and perhaps focus on the use of digital tools to get information and stories of heinous injustices out worldwide. After all, the Web has to be more than SuperPoking and dumb online videos on cats skateboarding.

Our session is aptly named: “Inconvenient Stories.”

My favorite kind.

Video, of course, to follow.
