Personalization: Future Internet Experience?

I found some articels talk about the future of internet and how personalization will play in the figure. Some articles discussed that web 3.0 (http://en.wikipedia.org/wiki/Web_3.0), would be all about personalisation.

I am not sure with that, but with a right implementation personalization is a great concept for people to experience the internet in a very different way in the near future. We could imagine that when the future internet becoming ubiquitous with personalization features, internet would recommend people about information they exactly needed right away, and tell them how or where to get it. Thus in such internet experience, information comes to people. An interesting observation on how internet evolves would be:

Web 1.0 : where people was looking for a centralized information

Web 2.0 : where people is sharing a scatered/distributed information

Web 3.0 : where people will be looked by information on anything related, anywhere, anytime

On another hand, as discussed in the following article,

privacy and security is still the most stressful area to be extremely carefully managed so people will not see such ubiquity internet as a threat to their personal life, but instead as a great experience that help their life better. One book that talk about such privacy management is as follow.

It discusses and give insights on some questions: At what point do personalization and privacy clash? Who owns personal information? To what extent should technology be constrained by social factors?

Web 3.0 is expected to be “matured” starting in couple years to come… so lets see what’s happening then…..
