It seemed to me that most speakers forgot that there are not only start-ups and big corporations but also a lot of people in the public sector. Web 2.0 is also becoming more and more interesting for learning platforms and marketing, and for plain access to information, in those sectors. Let's not forget that this sector exists, too.
Why not make the session information easily printable from the website? This would have been useful before setting off to Berlin. Instead it did not print well and did not work well at all in Firefox. This seems bad for a conference with a design stream that talks about usability and accessibility.
Most places seem to have a list of delegates so you can find out whether there is anybody you need to meet. Here you were forced into the social network.
As regards the facilities and organisation this has been very disappointing. Signposting was bad to non-existent. How about printing passes that let people at the entrance see what kind of pass you have without having to pull you over and staring at you. Why were people forced to wait outside the keynotes room until just before? Why so few seats? And why the awful lunch bags?
Why did I have to create an account again when I had done so earlier when registering for Web 2.0 Expo? It seems a little cumbersome.
