Autonomous and habitual movement to Facebook, Gtalk. It's quite amazing.
Often, when people have nothing to do online they move to FB just to see random stuff... It's quite appalling at a certain level, particularly when we think about human behaviour.
2-3 years ago, one would wait to get to know a person, one would wait to meet a person and one would be surprised to see another person after a long duration... Now, we really don't have to bother socialising; we can just go to a person's page and see what we like or dislike, it ought to affect the way we behave with that person.
Agreed that it is a fantastic way to stay in touch - but it is quite disruptive at a certain level. Privacy is almost unwillingly given up.
