Obsession towards Social Networking Sites

Is it a obsession or it has become compulsion that each and every person likes to flash him or herself on numerous Social networking site?

It can be both.. do we really have to display our feelings/happiness to outside world, which may result in tragedy or may be not or its just a fun part of our life

For few it has become prestige to be on social networking for few its complusion and for few its just a fun to be..but arent we seeing the pros and cons of it...we need to think about it.
