Facebook was a new revolution in social media when it became popular. It provides you a big field where you can make, you can contact to your old friends, you can share pictures and staus with them . Mark zukerberg invented Facebook for connecting with friends and then it became popular and then what happens each and everyone knows that how the craz of Facebook increased.
Now Facebook provided calling facility which is better than WhatsApp calling and other calling apps . I really liked the Facebook and now Facebook bought WhatsApp too. I suggest that if you want to be connected with your friends then join Facebook.
