Its been more than a year I use whatsapp and this is my experience sharing about whatsapp. I actually had limited friends earlier, but now my friends friend is also my friend because of whatsapp group. Whatsapp group helps friends to be in touch and it helps to share images, videos and to message.
Nowadays, I am not bothered if I do not have balance as its easy to call through whatsapp. I am the person who always updates my status and display picture. Its a good messanger.
Lots of awareness, Lots of informations are being shared through whatsapp. Also, on the other hand lots of rumours and unwanted informations are also being spreaded. Everything has its own pros and cons.
Its a great messanger. Lets use it for good purpose.
