While at the TED conference last week, I asked a variety of people in attendance at the elite gathering which presentation had blown their head off. Figuratively, of course!

TED–for Technology, Entertainment and Design–had an eclectic range of speakers and tony digerati parties at its new location in Long Beach, Calif.

Onstage, there were a lot of talks about the awful state of the earth at TED, which sometimes feels like a four-year college in four days.

But there were also less-dire presentations, like the one from “Eat, Pray, Love” hit author Elizabeth Gilbert about genius, and another on how Brad Pitt’s head and range of facial expressions are now stored in a studio database for all eternity (as part of his work on the movie, “The Curious Case of Benjamin Button”).

That’s a cold comfort amid all the global melting down, but BoomTown will not refuse it.

I also got reaction from some other TED attendees to the event. Included in the video are: Reid Hoffman of LinkedIn, Foxmarks’ James Joaquin, Craig Donato of Oodle, Mozilla’s John Lilly, VC Dave Hornik, Steven Levy of Wired, entrepreneur Bill Gross (showing off a future car) and techie Linda Stone.

Here’s the video:

And here is a video of my tour of TED action.

Here’s the second of two videos I did while in Amsterdam for the PICNIC conference last week.

The first video from PICNIC is here.

More biking along the lovely canals of this Dutch city, along with even more odd digital stuff at the conference, as well as appearances by Liberty Global’s Mike Fries, Nike TechLab’s Michael Tchao and former Microsoftie Linda Stone.

Here’s the video:

BoomTown is now right next to a canal–no falling cows in sight!–in Amsterdam, here for an unusual digital conference called PICNIC, which starts Wednesday and runs through Friday.

With sessions like “We Think: The Power of Mass Creativity,” “The Emerging Real-Time Social Web” and “The Future of Business Creation,” it seems to be a place for big, messy Web ideas.

Speakers from the U.S. include former Microsoftie Linda Stone, Amazon CTO Werner Vogels and Internet thinker and author Clay Shirky.

For PICNIC’s conference onstage, I will be interviewing Liberty Global CEO Mike Fries on the future of television, and the CEO of Vodaphone Netherlands, Guy Laurence, on the future of mobile.

But I am a little worried, after seeing this promo video for the conference, that it is a little too brainy for me (Warning to those who don’t like seeing heads exploding in a bloody mess!):

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.
