Zude invited me into the Web 2.0 Expo hall to see some new stuff that isn’t released yet. Damn, Zude is one of those things that you just need to keep playing with to get. They are letting you drag-and-drop all sorts of stuff from all sorts of places on the Web.

Think about building a mashup between Twitter, Facebook, Upcoming, Yelp, and other social networks. Now you’re starting to understand a little bit about how disruptive these guys are trying to be.

Of course, if you don’t think Zude is all that cool, I made a few videos at the Web 2.0 Expo yesterday. Here they are:

TripSay, a new site for vacationers.
My former boss, Lenn Pryor, who now is a VP at Nokia tells me about Nokia’s latest.
Moo’s CEO shows me the latest from the cool business card and printing people.
I get a neat tour of Blist, a cool Web-hosted database.
Amy Shuen, business school professor, talks to me about her new book on Web 2.0 strategy.
I get a look at Zloop, a new company that’s making a service for us to work together around projects. Part I, Part II/Demo.
Morfik showed me their new Web development tool, which builds rich internet applications.
DotHomes tells me about new real estate search engine.

Every time I walked into the Expo Hall yesterday I got pitched by PR people and couldn’t even get much passed the front door. So, when I got a chance, thanks to Zude, to sneak in after hours I couldn’t resist. What’s fun was Jeremy Mazner, PM on Microsoft’s Live Mesh team was still working there and we stopped to find out more about Microsoft Live Mesh. Of course, this is one time I can get a photo of the Google booth without being told off.

You probably won’t have a chance to visit CERN, where they are slowly turning on a new 27-kilometer-long particle collider called the Large Hadron Collider. Even if you could, they soon won’t give public tours down underneath into the collision chamber. So here MIT Physicist Frank Taylor gives us a tour. We’ll have the second part up next week.

This isn’t the sexiest video. It probably won’t make it onto Digg, but it will make you smarter about the science that’s going on that will probably dramatically change how we understand our world.

Along on this tour is famous science fiction author Bruce Sterling, who you can see in the background at about minute 5 and also Ben Segal, who was Tim Berners-Lee’s mentor when he invented the Web at CERN.
