I have to disagree with you in your description of Web 2.0. Your post makes AJAX and client interfaces the defining characteristics of a "Web 2.0" website. I'd argue that AJAX and smoother interfaces were an important component of what made up Web 2.0, but I think there was much more involved. I'd characterize Amazon as a very important player in the "Web 2.0" space, but even yet there isn't a whole lot of AJAXy-ness to Amazon's website. I'd argue the most important aspect of "Web 2.0" are/were the open APIs that make mashups other such web interactions possible, as well as the concepts of harnessing "collective intelligence" (or collective stupidity, as is sometimes the case).
I think I agree though, the next "layer in the stack" might very well be the platforms of the social networks. Whether all this is Web 2.0 or just Web 2.1 remains to be seen, but it is a compelling development.
