As I assume most of you will have one or two accounts in a social network, let us find out the following:
which social networks do you use?
how much time do you spend in each one?
what do you do there, i.e. what functionality of the social network are you using?
== Popularity Changes ==
A problem many social networks face (like MySpace and studiVZ for instance) is their short half-life, meaning that it is difficult for them to keep their customers happy. Popular social networks in Germany at the time of this writing (2012) were :
Facebook, studiVZ, Google+, wer-kennt-wen, Jappy, Lokalisten, StayFriendsAs you can see the popularity changes over time (Facebook has been excluded in this diagram):

== User groups and user motives ==
The new Internet-based communication changed the interpersonal communication dramatically. It moved from the private one-to-one communication to an one-to-many communication because of emailing and chats but also because of the „new media“ like social networks, blogs, forums etc. There are so many social media offers which meanwhile belong to the everyday life.
The reasons why people use the social web:

Social media users are almost everyone: women and men, adults and children. In Germany there are about 74,7 million people online. And the trend being online increased during the last years.
Most of the users are between 14 and 50+ years old.

1. The digital outsider

They are at the age of 60 years and don't see any reason why they should use the new media., maybe because they are intimidated by the diversity.
2. The occasional users

This people use the social web very rarely. They know about the basic components and use the social web only for gather information.

== Risk & Abuse of Social Networks ==
Internet social networks are nowadays great places to meet and for people sharing similar interests. But Facebook and similar Social Network sites can also pose serious security threats to the users, and ways for others to abuse these lacks of security.
For a little practice-relevant demonstration read this short story about a student, who is very active in social networks and got into much trouble.
Social Networks can cause a lot of damage to their users, but in most cases the users are themselves to blame for wrong behaviour.
Harm for Job & Applications : If profiles are public to every one, personal managers also have access to the posts, photos and interests of the employee or applier. If there are compromising contents to find, this might have consequences to the employees job or appliers consideration.
Crime : Social Networks are places for people with criminal intent, they clan collect data of a targeted person and can narrow down when and where this person is located at a specific time. This leads to an easier way for burglar to commit adultery.
Violation of copyright: If a user uploads a picture, which is protected by copyright, he can get charged for this violation of copyright. Even if a user uploads a picture to a friends wall, the friend might has to deal with the emerging consequences.
Online - Mobbing: Exclusion form groups, insulting or offending posts on walls, informations are used to expose targeted person (Cyber-Stalking).
Lack of data privacy protection: some Social Networks collect every data they can get from the user. The networks sell this information to companies which want to personalize the adds for the user to generate buying power. Some not only collect data of the registered user, they are also collection data of non-registered users. An example is the facebook app, which allows the users to sync their phonebook with their facebook contacts.
Social Engineering/Phishing : Through phishing third persons get login data to acounts to impersonate the specific person. Most of the time the intent is to ask for financial support of the person’s friends.

There is a web site called Google Flu (http://www.google.org/flutrends/) which predicts flu epidemics based on search term people enter into their browser. However, another interesting approach is to use social networks:
Nicholas Christakis: How social networks predict epidemics, (http://www.ted.com/talks/lang/en/nicholas_christakis_how_social_networks_predict_epidemics.html) (17:55 min)
== Ethnography ==
"Ethnography is a qualitative research method aimed to learn and understand cultural phenomena which reflect the knowledge and system of meanings guiding the life of a cultural group." In her talk at TED Stefana Broadbent tells us how communication technology is capable of cultivating deeper relationships, bringing love across barriers like distance and workplace rules.
== Advantages and Disadvantages ==
Networking with friends
One advantage of Social Networks is the network of friends. It is always possible to be informed about the current activities of your contacts. In addition you can keep in contact with friends, which live far away. Or you can find friends, which you have not seen since school days.
Facebook and the other Social Networks give you the opportunity to communicate with others. The easy way to write massages and answer it, makes it possible that every day many messages and comments will send. To stay in contact with friend form other countries isn’t a problem because 798.9 million users from about the world are at least once a day on facebook :
. If you agree with someone and you want to publish it, the easiest way is to switch the like-button. On facebook you can also use the live chat or the video chat for communicating.
Fun and Entertainment
Another reason for using social networks is the offered fun and entertainment. For example you can play Social Games with your friends.
The network XING gives you many positive feedback when you searching for a job. On XING you can create your own profile with working data for example which programming language you know. Employer can use a search option to find qualified employees and they can also easily get in contact with them. As opposed to facebook where an open profile can be a disadvantages for a career-orientated person. Your boss can get too much private information on you and this may have consequences for you. If you looking for a job in another country the network linkedin will be the right choice.
With the modern achievement of smartphones it’s easy to reach people every time and everywhere. You can quickly get every new of your friends on your mobile device. In contrast to the conventional short messages on a mobile phone you have to pay nothing per send message. But there is also a disadvantage due to the constant accessibility expect many users a fast response.
Another advantage of Social Networks for companies is the advertising. It’s possible to create a profile for your company or for a product that you want to promote. People who had made a good experience with this product used to click on the like-button and everybody of her or his friends see it. So it allows reaching many people you on an easy way. It’s also possible to create your own user-related advertising. You can define you target group with age, gender, hobbies, interests etc.
A major disadvantage of the Social Network usage is the lack of privacy. If it is your first time on facebook you should check your privacy settings. These settings are often confusing and opaque. It is also important to think carefully about which parts of the profile is published on the internet. Something that is published once in the internet cannot be undone.
