What is Web 2.0 2.0?

My answer? Web 2.0 = Web Bubble 2.0 = Bubbly 2.0. I want some. Om has others:

Last night, I was at a dinner, where one of the topics of discussion was Web 2.0. More appropriately, what is Web 2.0? It is a damn fine question, and difficult one to answer. D. Keith Robinson writes, “Depending on who’s using the term, you could be talking about the Web as a platform for applications, a philosophy in building and designing Web applications, a group of powerful Web technologies, and much more.” Mark Sigal says, “At the core, it is an applied web service model that blurs the line between software and service.”
Dave Winer says, “Web 2.0 is a marketing concept used by venture capitalists and conference promoters to try to call another bubble into existence.” Richard McManus has his own take here.
From my perspective, I define Web 2.0 as a “collection of technologies - be it VoIP, Digital Media, XML, RSS, Google Maps… whatever …. that leverage the power of always on, high speed connections and treat broadband as a platform, and not just a pipe to connect.” Clearly, Web 2.0 is different and many things to many people. What is your definition? How do you view it? Curious to find out, especially before next week’s Web 2.0 conference.

Am excited to be going to Web 2.0. Not because of any major new insights or product launches (cheaper and more efficient to just read the blogs) but because to be at what should be an electrically-hyper event, of the kind I missed out when I was discussing trade policy over long lunches at the European Commission in the Web1.0 bubble at Millenium's end.
