I know we have tried to address the definition of what the web 2.0 means. Some people tend to use a 1. technological definition (AJAX and so on). 2. Others use the social component of the application and mix with the first definition to create mash-ups. 3. others finally talk about user generated content. Not an easy task, and depending who you talk to, or what you are talking about, you can use any of these definitions. I recently wrote an article on the topic for the alumni association of French engineering school, Centrale Paris. It should be published in the upcoming months in a special issue (Thanks to O. 
).
My point today is that I myself don’t really know what definition to use. I like of course David Hornik’s definition of Triple-A. But indeed when you have a look at www.netvibes.com: it’s so web 2.0, you just know it. No definition required. Or www.wikio.fr, so web 2.0 again. Tariq mentionned www.MusicMe.com tonight, and I thought, oh, trying to be web 2.0 also ? (I had actually never looked at the site, although it’s CEO Freddy Mini had been on vpod.already, and that Pascal Mercier has mentionned the services gazillions of times…).
So the usual question: what companies are really web 2.0 in Europe these days ? Pierre Chappaz tried the quiz the other day, but I tend to think that too many people registered saying they were a web 2.0 company without much justification. Please reply in the comments, with a justification of why you think this or that company IN EUROPE, is part of the movement… or not.
