Pete, I think you're missing the point.

I don't see marketers pushing anything about web 2.0. I don't hang out in those circles.

It's not any sort of sales tactic or associated with any type of product you can purchase so I'm not sure what you are getting at there.

It's all about user connectivity and user generated content and building communities where users can interact and share. It's about websites built and directed by it's users in real time. (or at least that's a big part of it without getting too deep into it)

Take a look at the top 10 websites in the US and tell me if you see any web 2.0 stuff there....

-Yahoo
-Google
-MySpace
-Microsoft
-eBay
-YouTube
-Facebook
-Wikipedia
-Craigslist

Most of it!

And the "heavy" web 2.0 stuff on the list we had never heard of a couple years ago - MySpace - YouTube - Facebook - Wikipedia

It shows that web 2.0 is what users are looking for and demanding.
