Blogging : a Necessity

what do u think , is blogging a necessary thing to the mankind for developement as humans? if yes, why so & if no, why so?Ii think yes b'cos lack of communications amongst the people dispersed globally has set a great distances between their relations.hence can mislead the path of life.the sharing of ideas ,at certain times from unknown people,can change the lives.and till the eend we never know who did it,his religion,race,caste,creed,sex,etc.sounds interesting.yet it might be a truth. if it has happened with u even slightly please share it how.
