Once upon a time there was orkut which was very popular social networking site in the world then facebook comes into the Competition facebook gives better interface better security option better service and support.
Service and support was very good at that time of orkut but now orkut totally finished.
Orkut is basically social networking site where you connent with you family and you can chat with them.
It takes lots of time to load and it is very slow. Interface is not that good.
