war of the social networks

One of the most controversial elements in the whole web 2.0 world is most definitely the whole "social network thing". As most of young people nowadays use social networks very frequently, not everyone sees the social network sites as a blessing, claiming corporations exploit the information given by the user for profit.

But one fact remains undeniable: social networks are everywhere. And every single one of them is trying to be the best/biggest/most successfull. Especially in Germany the battle is on. Some networks now try to attack the leading community studiVZ. Especially the social network giant facebook is really pushing forward. With a big marketing campaign including a facebook party in munich, facebook is going forward to get more german members on their site.
However facebook is not the only one trying to get to the top of the social networks in germany. The community lokalisten.de is also eager to get tot the top. With a major media corporation in the back they are now trying to pull people in the competetive way.

Anyway. I'm interested to see how all this competition turns out. Will there be a winner? Will one day all your information be in the possession of a major corporation? Will you have to maintain several accounts just to stay in contact with more than one person.
