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.
