Google would have taken a sigh of relief. United States is now the second largest Orkut Using Country which just jumped ahead of India. Orkut has been criticized and termed as a failure in the US.

Here is the latest orkut demographics report
You can check orkut demographics anytime by checking Orkut Demographics Page and stay updated with recent orkut trends.
