Social Network - MyBln [ http://mybln.com ]
One of my friends happened to introduced me to a social network site recently and asked me to join as she liked it a lot. The first though that came to my mind was “no more social network site”. I feel so saturated and addicted to the social networking sites of which I am already a part of. But the curiosity to know how this new site is proving to be different from all others and actually attracting people to join in led me to this site. So I entered the site called ‘MyBln.com’.
