Web 2.0-ness

First let me say that I miss OSCON terribly this year. I've been for the last two years and enjoyed it a great deal, but with the Italy trip this year, it just wasn't in the cards. OSCON is the annual open source convention, primarily for practioners, and I enjoy going to it and reflecting on what is new. It is a great way to remind a professor that the state-of-OUR-art actually begins in industry, not in academia.

One of the memes from last year's OSCON is still generating much buzz: Web 2.0. Now Tim O'Reilly has a nice posting that attempts to delineate the various levels of Web 2.0-ness. He asks and answers: What makes the difference between the "2.0-ness" of Flickr, Ebay, and wikipedia? And where does Amazon fit in all this? It's a nice article and very clear.
