Off the top of my head.. I know it's meant to have made kids have less empathy nowadays, less self-confidence and generally more narcisstic.

Well as in social networking websites, it has had many effects in our society. In a negative aspect, everyone depends on facebook and are become less social physically and more social electronically. People don't keep anything a secret anymore, they go on twitter and facebook and reveal their problems there. Its fun and all, but its addictive.
