There is a new trend in Indonesia and it is an application called "WhatsApp". It is an application that allows us to send messages to a person or - more frequently - a group of people. It is a replacement of BlackBerry's BBM. The BlackBerry's era is over.
The reason is that Android is becoming more popular, as in other parts of the world. WhatsApp is cross platform and operator neutral. What more could you ask?
I don't use BlackBerry, so I don't use BBM. I just recently bought an Android phone - it's an LG. WhatsApp is the application I installed and quickly I am part of many WhatsApp groups. I could see that many people are like me, embracing WhatsApp.
