ConclusionConclusion
StudiVZ-Users voluntarily reveal a lot of information about
themselves to the internet community
change of the boundary of private and public information
especially among younger people
some correlations with relationship status, almost no with gender
only some support for personality differences:
the StudiVZ-User is more likely an outgoing extrovert than an
anxious neurotic
StudiVZ as the daily drug for „contact-addicts“?
finally: is it just fun and entertainment?
