According to wiki:- “A social network is a social structure made up of individuals (or organizations) called “nodes”, which are tied (connected) by one or more specific types of interdependency, such as friendship, kinship, common interest, financial exchange, dislike, sexual relationships, or relationships of beliefs, knowledge or prestige.”
But what are the useful services that all the leading social networking giants are providing now? Does it really worth for people trust and use as it a part of life. Are they really useful?
Yeah they are. But the complexity of the issue is not as simple as it seems. It took a little time to become what it is now. It has been a continues process of develop , adopt and evolve a culture of what we are now enjoying. Still it raise too many questions like what now, next and how?
