Going by that, and given that I have 1272 friends, it means I actively follow the news on 101 friends, communicate with 50 (and a half, heh?), and keep in close touch with 25? But I only closely follow maybe 1-3 people! But I definitely communicate with more than 50 - through status comments, quiz comments and what not - apart from wall posts. Well, I guess it's a fair generalization still.
I'm most interested to know if the researchers can really come up with algorithms to friendships, or at least virtual friendships, because I believe that is impossible. It's all just random!
Another concern for me is, how do the researchers get their guinea pigs - the people they carry out research on? Like, let's say they want to study me because I'm such a "Facebook whore", would they just get access to my information without my consent? How many people I stalked, clicking through pictures, and viewing people's wall-to-walls and what not...
Or would they ask me first? If they do, and let's assume I say yes, does that mean I will be giving them access to my friends' information as well? Because - I think I raised this question before - who owns this data?
Naturally, Facebook terms and conditions stipulate that the users have no rights over the information, but still, it is information about ME! And while I still own the content, the statistical information could be useful too. If anyone else has a right to view it, I should be able to view it first! I also want to learn more about me and my habits!
Yes, after going through the Facebook principles, I think that any information that is provided to advertisers and marketers should be provided to me first.
