What's Web 2.0?

I've been wondering about this for almost 4 years.  Every time I think I've got it figured out, something changes. 

There definitely are changes underway on the web that impact how we will interact with it, and how we will interact with each other using it. From the business book perspective, I feel what's being called Web 2.0 is worth investigating.

I believe that there will be significant business rewards for those who figure out how to apply Web 2.0 tools and techniques.  I'll certainly explore that in the book. 

In the meantime, I've decided to migrate my business from Web 1.0 to Web 2.0.  I'm not sure yet what that means in terms of cost or workload.  Learn at my expense!
