Good topic!
i think people have an insatiable, permanent need to connect and socialize with others, so platforms that enable communication will always be in demand and are useful. on the flipside, social networking sites are also now breeding herd mentality...people find it hard to actually differentialte themselves and they go to great lengths to do all kinds of desperate rubish to get that effect. plus, companies make money off socializers.look at fb....will always be free, but it now has a stock ticket symbol. plus, u cant socialize too freely bcos everyone and their mom is watching your every move, so freedom is kind of limited when people connect publicly with too many people. i hate them but love them to be honest. ok my rant is over!
