‘The world is getting smaller’. What does this mean??

The world is getting smaller. I think that the world is getting smaller throughout the use of the internet. I think that nowadays lots mor people know others than the did say 30 years ago. This is all because of the internet. Engines like MSN, Facebook and Myspace shrink the world because of the way they connect people.For example; if it was real life and some stranger comes up to someone and they are drunk and on drugs often that person wont want to make friends with this stranger. But on Myspace or Bebo is a stranger is drunk or on drugs you cant really tell. So it would be more likely that someone would make friends with the drunkard online.
