Ok I paid the 1 buck, or agreed to pay a year later. Those days I lived in India, and my friend kinda forced me to use whatsapp by selling it. I still remember sitting in an auto-rickshaw and downloading the app after the sales pitch :) This must have been 2012, but could it be earlier - maybe.

Point being, I agree with you, it was getting that adoption anyways, even with the fees. And within months, I was hearing this from so many others.

How do I remember? I moved back to US in Feb 2013, so it had to be before that, just can not recall the exact year and month.
