... we could know immediately the internet profiles?

If we would have an interface with all the informations of our internet profile, and everyone that we meet could see it, how will be our life?

In internet there are really an high amount of information about us, like what we bought, our comments on facebook, health records, banking transations, the music that we like and so on. Knowing all this sensitive information would be a serious problem for our privacy, the people could learn a lot about us from the first meeting, and someone could also fool the others.
Actually we are not too far to this point, infact the most curious do research about the facebook's profiles of the people after their first meeting, reading the last informations and learning something about us. If carried to the extreme they could read about years of our story, what we like and what we think, in short  everyone could know an important part of our life. And the implications would invest several side of our existence. Imagine to go in a bar for drinking a coffee, you could know the believing and personality of the people around you. Maybe reading a profile don't permit to know everything, but is enough to can say which kind of person we have in front of us.
The good consequences of this could be that we would know the strenghts and the difects of the persons from the beginning, avoiding in this way the bad surprises that often we discover about the others only after a long time of slow knowledge. We could choose to talk only with who are similar to us, who likes what we like, and it should be really easy to break the ice. Knowing the story of the others would permit also to know what we have to expect, which kind of actions are a taboo, and what the others like.
But where will finish the pleasure of the discover? It's difficult to understand the behaviors of the others, and this often is annoying and frustrating, but this is also something that make the life more interesting. Discovering the behavior day after day, wondering about the reasons that make the person like they are, is something worth to be lived. Don't knowing how is a person will give to us bad surprises, but will give a life more enjoyable and interesting, because sometimes the best are the people really differents from us, with which usually we don't would talk with.
From the differences and the contrasts we can learn more about us, and we can grow enriched. Another aspect to consider is the importance of the privacy. Make public everything about us could be a bad experience, could hurt, and if there is something that we don't want to talk about, some secret that we don't want to share, they have to remain private.
In a world in which everyone could read everything about us on internet, probably the only solution would be... don't write nothing.
