The last decade shows that more and more peolple want to "take part" and "have something to say" instead of just sitting in front of the TV and just "receive". They don't want to "hear" news, politics or the latest thing, but to "be" the news, politics or the latest thing.
"Interaction" is the magic word here.
And as the world gets smaller, distances irrelevant and information digested with great speed, the internet will give an even bigger opportunity to investigate the "inner" world.
