Maybe you have heard about Web 2.0 or the next generation of Internet but wonder what the fuss really was all about. In essence it is not a single thing but a concept made possible by a few different technologies. The thing is though, that it is not so much about technology as it is about changing the way we do business, interact and collaborate. I think just a superficial understandning of these concepts makes it much easier to envision new ideas of how to create (IT-based) service that help us all do amazing things. Someone have put together a very nice video which does a good job of explaining this I think

Web 2.0 … The Machine is Us/ing Us

It is just 4 min and 31 sec and it is well worth it – especially if you are not a technology kind of person.
