At one stage I actually thought that I was part of a hidden camera jest.

I have never experienced such gastronomical terror, as when I sunk my teeth into the would-have-loved-to-be-a-sandwich-but-never-quite-made-it and subsequently drank the nearest liuid in a desperate attempt to save my life. Unfortunately I was exposing my body to the black-fluid-which-has-yet-to-meet-a-coffee-bean.

Although andreas might have a big brain, it is unfortunately dwarfed by his insanely big ego.

Never before have I seen a man putting such an effort into stage setting himself at a conference.

He completely ruined several interesting panel debates by spending more than 30 minutes of the one hour sessions talking about him self in a veeeeery sloooooooow and annoooooooyyyying voice.

Please, please, please never use him again

The place of the expo was not very good.
Too much space between the areas - very confusing ways - very very bad air.
There are better locations - even on the fairground of Messe Berlin - Messe Nord.

I'm freezing.

After having attended 4 days and 17 sessions I lefted this years event with a bit of scepticism... like in a vacuum. But after a few days and after having shared my learnings, inspirations and my outlook from the conference with friends, colleagues and likeminded, I've found some of the value-for-money I'd hoped for.
It's when you do your storytelling based on your experiences that it becomes clearer to see the perspective of the great power this media represents.
It can be expensive and hard work to climb a mountain, and it's not before you stop and take a view you know why you're doing it...

As a web marketing manager representing a large international manufacturing company I was quite surprised to meet several speakers and sessions only addressing or appreciating Entrepreneurs, VCs and Journalists. I spoke to at least 3-4 others who was left with the same impression.
An idea for the next Expo event could be to make sessions and key notes targeted directly to the attending segments. After all that's what Web 2.0 is all about... listen to the masses and give them what they demand.

I found the Expo overall interesting, and liked a lot the workshop, "hands-on" model

But I think that the entire category "media" was missing: except for one (small) panel about newspapers, there were no experiences / case studies / experts / storytelling etc about big media companies - or from them

How is Web 2.0 applying to traditional media's Internet strategies? Newspapers, televisions, etc. What are they doing, and what are they not doing (and why)?

I think that this would have been a very interesting line

A topic that i expected to be big at the conference but didn't see at all was the problem of getting benefit out of data-mining vs. pushing herd behavior.

Will the users behavior be negatively influenced by early published results from data-minined peer-data?

Tim O'Reilly blogged about this in context of the inbreeding techrcruch-top-bloggers.

What are techniques to avoid this?

Where was the discussion about this?

i think that privacy and data-security was vastly underrepresented at the conference.

How can we keep the users confidential data secure?

What to do to minimize problems for the users that gave us their data in case of a security breach?

Web2.0 companies are trusted with a lot of data from a lot of people and should show some foresight by thinking about problems that could arise from that.

Great sessions in the keynotes area, specially the interviews with tariq krim, the Kathy Sierra speech and the "entreprise 2.0" by the author of wikinomics

I think the first day was the better, the sessions were longer and the speakers can go deeply into the themes they talk about.

The overal sessions were ok but i think that the sessions in the future must be longer, i speak to some people at the worshop and all of them think the same way...the topics were covered but the need more information.

Hi;

Some keynotes weren't really relevent to Web 2.0, or at least the speakers didn't make the relation so clear.

Will the keynotes be available for online download? That would be really great.

Hi there,
first of all: Thank you very much for bringing the Expo to Berlin. Speakers and topics were well choosen.
But unfortunately I couldn´t feel the spirit atmosphere of WEB 2.0 during my stay. It was more like visting a finance expo.
For me the WEB 2.0 Expo startet at 9 am on Monday, drooling over coffee. I found myself in presentation room with no windows, no inspiring decoration and a poor guy on the podium trying his best to get the audience´s attention. His desperate calling for collaboration died away in the darkness of the presentation room.
Next time, please think about all the creative tools we know form applied social studies like open space workshops, small groups brainstorming, audience guidance, center mapping etc. And please: Think about your presentation room designs. Classroom seating does not really fit the WEB 2.0 ideas.

Reconsider your location as well. The huge and "calculating" buildings of Messe Berlin is not a geeking ambiance. Every nursing home is a better think tank. Think about your decoration, large market places, the idea of the speaker´s corner in London´s Hyde Park, bill-boards etc.

There were so many interesting people (investors, programmers, designers, start-up....), but your expo design was prejudicial to the ideas of WEB 2.0 like sharing knowledge and experiences, bringing people together and last but not least givng ideas a chance to be implemented.

Anyway, thanks very much for the expo and please go on.
