I've come across one interesting thing. Social networks became the subject of bitter argument as they were suspected of having provoked a set of riots in the UK. Of course, in the world of telephones, emails, icq, skype and other developed technologies Facebook and Twitter are the chief instigators. Hehehe. That's the reason why the UK government cherished a hope to ban the social networks. And otherwise, they are strategically important for the power because of their growing influence on people's mood so the authority is sure to cultivate this inexhaustible source of putting pressure on our mind. Dear Facebook and Twitter, take care!
