Is this a total waste to society? Could the Arab spring have happened without such social tools? Is the world a better place when common people are empowered to fight against perceived repression?
I'm not taking a stance on those revolutions will affect their countries. I will say, however, that a government that can protect itself against revolt has little incentive to look out for its people. Society can be made 'better' in many ways.
The "strong tie"? I'm just not so sure changing the "weak tie" is such a net positive for society. I'm not going to claim that FB doesn't have its positives but I'd rather see a society building strong ties with fewer people than weak ties with many. (and, frankly, doing nothing but wasting time for hours per day)
I prefer society, via technology, to continue to have and explore both.
It's funny because your entire comment is self contradictory. On one hand you criticise socialising using Facebook and on the other want to build stronger ties. Socialising = Stronger ties.
I criticize the assertion that changing weak ties, in the way FB does, is a net positive for society. It's one thing to reconnect with an old friend, it's another to spend time everyday browsing through pictures of people you haven't seen in 10 years. Too much of the latter happens on FB.
