Recently, I was reading a post on WhatsApp its current phenomenal growth sans a revenue model. There was also some banter about why Facebook paid $16 billion to acquire it and then the rags to riches of how its founder Koum lived off food stamps. Coincidentally, soon after that I heard & witnessed stories of how people are using WhatsApp all indicative of a swirling economy that is probably a simple cash pile for Facebook. Of course there is still a need to carry out small experiments that can subtly integrate services for its loyal user base.
