What is Web 2.0?

I've been asked about the definition of Web 2.0 several times recently. Thus, I've become hypersensitive to how other people are viewing it.

Today, I ran across a rather eloquent definition at Axel Schultze's blog for his new company, Xeequa.

"Web 2.0 is not a new release of the Internet - Web 2.0 is the culture shift from view to act, from find to share, from passive to collaborate."

Thanks Axel.
