Justin Krause makes his point on how facebook’s timeline might overshoot the mark:
People, and their online identities, change. The Timeline, by capturing and cataloging all of our past activity on the site, prevents us from ever cutting loose and starting over.
I don’t want everything I do to be catalogued forever. I just want to be able to share things with my friends, and then move on with my life. Thanks to Facebook, my online identity won’t be moving on with me.
