Social networks conversation questions

Social networks have always existed, but the advent of internet has led to a "new" way of setting up and maintaining relationships.

Social networking services

 * How many hours a day or a week do you spend on the net when you are not working?
 * Do you use social network services such as Twitter, Facebook or LinkedIn?
 * If you do
 * How often do you use it/them?
 * Why did you choose that particular service?
 * When did you join your first social network? Does it still exist?
 * What fraction of your friends in social networks are real life friends?
 * Do you have any real life friends you met through the internet?


 * If you don't, why not? Do you think you will ever join one?
 * Do you ever get on the internet using your mobile phone?
 * Some people don't use email anymore, because they prefer social networks. What do you think?
 * Some people "collect" friends in social networks. Is it possible to have 500 friends in real life?
 * Do you think Internet addiction is a real disease?
 * How different would your life be if there were no Facebook, Twitter or Instagram?
