I was reading the news this morning and I couldn't let this one get away without me posting it on my blog:
There are lots of interesting things that happens in a world where things you do are more publicly accessible. It's similar to the keynote speech by Jon Kleinberg I've heard during the last SIGIR: all the 6-degree-separation endless discussion has to be revalidated. Now that social networking sites makes your social network publicly visible, all numbers and goals change. It's much easier for a person living in a cave to have hundreds of friends. On the same lines, it's much easier for a person that is trying to know more about another person to find people or direct evidence out there. In the past you had to hire a private investigator or things like that.
I could now start reciting a number of science fiction authors that predicted this shift on the concept of privacy, but I'll just end this post and start my day.
