Mass migration from orkut towards facebook by the elite crowd of India?

I have joined facebook few days back after receiving tons of invites from my friends/contacts.I have noticed with all my surprise that lots of my friends have migrated to facebook from orkut.Alexa has already ranked facebook No.22 in India.By opening the APIs facebook has created a platform which empowers the developers to plugin features into facebook and get noticed by 30 million people connected to it.
