The social networking sites are a means of relaxation after a hard day of work, after a hard fight with some one and after a prolonged boring conversation with a friend or with a neighbor!
You may “clipmarks” your interests and share it with the rest of the world! You may even tag your “delicious” stuff or simply “fave” your likings and share it with the virtual community!
You may meet your “classmates” in one of these sites and you may even maintain a “Live Journal” in one of these other sites!
There is something magic in becoming a part of the social networking sites!
