MY Social Media , What privacy

In  today's world we spend more time on social media than actual friends. We post about everything on facebook or tweet about it. Whether be a movie, review, book, app , restaurant , food  or even the  service or parking!
Be happy or sad, frustrated or enthusiastic, everything is out there in the cloud...
The more likes or comments we get the more excited we are. Gone are  days of picking a phone and calling a friend or family . The thought of just texturing and posting our status to let our friends know gives a complete different thrill..
To compete with the current social media , more are emerging , and more will keep emerging as technology advances.
Social gatherings have gone virtual  , we need to find an occasion to meet be it Super Bowl or July 4th . Ironically, even these gatherings are getting small.
Privacy has no importance in the social network world, today's prank can cost tomorrow's future..
The thrill of posting and updating our status constantly overrides the privacy factor all the time
It is not all bad about social networking... We can now read the reviews posted before we decide on a movie or a restaurant or a brand too!
This is putting the retailers and food chains on their food in looking more deeper into service, quality , quantity and the experience . CRM is more challenging with the freedom of posting on social media. The expected   service and support from these vendors has improved dramatically, which is helping the customers a better return on their money . In other words "Service what to say ---- Money well spent"
On one hand , the benefits of posting individual's  thoughts add value and importance to future preference and requirements , on the other we are tied down to what others believe and think. What do we know about their lifestyle and experience
If the concept of social media is to connect with people then why is the distance more in actual meeting ?
Our life being ruled by social media has led us into a world of worldwide friends, yet very alone and dependent on social network......
How safe are we with social networks and our privacy?
