Who hate social networking and have no account on websites like facebook, myspace, twitter etc.

Why do you think it is a waste of effort and time? Or, is the reason something else?

I hate it because its fake. People friend request you just so they can add another number to their amount of "friends" rather than actually try and pursue a friendship or keep in touch. The intentions of these sites are good, but the green monster of snobbery comes with it.
