Endless list of friends, known, once known, just seen, unknown...the list is really endless and thats social networking all about. The sites offer a voyueristic pleasure of intruding into someone else's private life and this keeps them in business.
I think its like the narcotics...once addicted you crave for it, more and more. I met a college kid while travelling to Tiruchirappali. Six hour journey by bus, I killed time mostly by watching this kid's activity. He had a mobile application hooked on to the networking sites and he was into his own customised world. In the mobile-network fringe areas, when the data got disrupted, he got so frustrated and restless in his seat. He was into a virtual world where one need not yearn or earn for pleasure. Once he said he had lots of friends, three hours later he said he was all alone!
Now who is to blame? The social network sites? users? society?
