Your article on Web 2.0 serves as a definitional resource for me and has helped me to understand the principals of Web 2.0. The comparison chart and Web As A Platform map are particularly useful.
I referenced your name today in an entry on my company's blog, tying Web 2.0 to the real estate industry. Please view the entry here: http://onboardllc.com/OnBlog/.
Thanks again for writing such a thorough, easy to understand piece on the direction of the Web.
