I’ve been looking around for a good definition of web 2.0. I don’t see any simple answer that encompasses all that it is. However, I did come across this article at O’Reilly which is arguably the best, most comprehensive discourse on the topic — if for no other reason than that these are the guys that coined the phrase.

Two Volvo ads caught my attention in the last 24 hours. Really, that's quite a great thing, isn't it? A company wants to attract your attention. The one last night, on TV, made me laugh. Here's the angle: It's about how crowded it's getting, too many people, and 300 million people is getting to be too much. And some experts are saying that Volvo is at fault. And you can see why in their ads, ... "Volvo for life". So, the insinuation that Volvo contributes to the world's overpopulation because they're so safe just made me laugh. In a good way.
