Last few years can be called a “social networking era”. Just remember the rise ups (and depressions) of myspace.com, linked.in etc. These networks are now completely shadowed by FaceBook and Twitter. Even when myspace and similar networks are not that widespread today, they were at the beginning of all. It becomes more and more usual to identify a real ego with social network profile. That’s not too dangerous in its basis, but there’s a big problem – people completely loose a sense for their privacy on internet. This is not an attitude against social networks, it’s only a thought about dangerous habits appearing with the social networking phenomenon. The risk is not the existence of social networks, the risk is how people behave there.
