And? The more important information would be the conversion rate of users that have been asked to pay. Whatever it is, they're still miles ahead of instagram/twitter/snapchat ever charging for use.
While this writeup may be meaningless in the long term it's still nice to see in comparison to other apps of the "moment".
How do you do that?
I paid. I had no intention of paying until I realised Vodafone Spain charged me 80 cents (euro cents) for a text to my Mum in the UK. A text conversation between us had cost me 8Euros, and some of them were just yes / no replies. After that Whatsapp seemed like a bargain.
