Sul blog Backreation la fisica Sabine Hossenfelder riflette sui molti siti di social networking che ha provato e si chiede a cosa possano servire:
Yesterday, I have given in to peer pressure and curiosity and now have a Facebook account. Feel free to add me to your friend list* and write on my wall, but don't count on me to be too active there. I don't even know how many different accounts I have!
Is all of this actually good for something?
