What's the Difference?

I'm a bit off-topic once again here. But I just retrieved some notes I took at a conference last year where we sort of defined the differences between web 2.0 and the previous -which we were calling web 1.0 :

Web 1.0:
-had static pages which were mostly code-based (HTML)
-for communication they just had feedback forms and guestbook signing
-information was basically one-way (publisher to you)

Web 2.0:
-the pages are dynamic, consisting of HTML, XHTML, Java, Flash etc.
-communication is not just back and forth, but multi-way. Publisher to you, you to publisher, you to world
-information is at minimum 2-way but usually mirrows the communication aspect goinf in multiple direction through the use of blogs, wikis and other tools.

we also came across Commoncraft, which you may find to be a great source for simple explanations of just about everything, including web 2.0 tools are. But be careful! it's easy to get "caught up" there and before you know it, you've been there for an hour..or even longer!
