At first we heard a wikipedia definition of social networks in general, I don't want to rewrite it so check it out for yourself:
As a next step we had to answer following questions:
1. Which social networks do you use?
2. How much time do you spend in each one?
3. What do you do there?
The answers to the first question wasn't really surprising, almost everyone is using Facebook.
More interesting was the answer to the second question. Most of us claimed to use Facebook only 1-2 hours a day, well I guess some might say the truth but I think a few among us didn't want to admit how many hours they really spend on Facebook, or they don't want to admit it to themselves :D
As to the last question, mostly it was posting pics or communicating with friends or relatives (especially ones who are not in Germany).
The next step in our lesson today was the popularity changes in social networks.
Do you remember studivz? Or even schuelervz? Yeeees those were the social networks BEFORE Facebook :D
As you can see, social networks have a big problem in common: it is hard to keep the users happy.
As soon as the user isn't happy anymore it is only a meaning of time till he goes over to the new trend in social networks.
I for myself was in studivz for a period of time, even after Facebook came up I still didn't just move over to Facebook (as FB for me was not so promising^^) but after most of my friends moved to Facebook I didn't really have any choices left...
The last part of the lesson was about a site called "Google Flu" which is a web site that predicts flu epidemics based on the search terms the people enter in their browser.
I thought that was very funny, as I would never search "flu" when I have a flu, but apparently lots of people do, and the predictions weren't even that far away from the truth :D
We also watched a video about how social networks predict epidemics by Nicholas Christakis:
Well thats it for this lesson. Have fun reading :)
