The unceasing Internet evolution is changing many aspects of our daily life, both personally and professionally. Internet is an extension of our potential, we are experiencing this transformation day by day. In particular, there are two main areas where this change is more tangible: communication and knowledge.

We now communicate in a very different way from how we did it years ago. Today chat, Skype and video conferencing seem to be routine; we take for granted the ability to communicate for free with everyone we want, anywhere in the world, relying on network services. We also think and learn in different ways from how we did it time ago. When something is unknown to us, we look for it on the Internet: researches on Google and Wikipedia are part of our typical day, to imagine a world without the Internet appears to be pretty hard.

Based on real cases and tracking the main web services trends, this presentation summarizes the impact that Internet evolution had, has and will have on us and in particular on the way we learn and think.
