Hi there, Remember the guy that announced a forecoming release to the research community of a huge dataset of publicly available facebook data? Remember many of you guys have disapproved of this idea for ethical reasons? Well, no big surprise, he was asked by facebook to destroy his dataset. But this genuine experiment yields an interesting question: <quoting Pete Warden> In an ideal world, we might not want any of this data to be public at all. At the moment it's easily available to commercial firms, but not to researchers, which seems like a bad deal all round. </quoting> http://petewarden.typepad.com/searchbrowser/2010/03/facebook-data-destructio... _ Christophe Prieur, prieur@liafa.jussieu.fr Liafa, Université Paris-Diderot http://liafa.jussieu.fr/~prieur/ [user experience research, social networks, (large) graph algorithms]
