That was the genius of WhatsApp really, they recognized that
messaging apps are all about network effects and instead of
focusing on the comparatively small market of the ‘developed
world’, instead targeted the other 3 billion people who don’t have
smartphones. And at that they have been supremely successful.
If you are anywhere apart from the States, WhatsApp is the de
facto standard for messaging. Here in Rwanda, it has far more
penetration than Facebook, it is used by literally everybody who
has a capable device. That came about not by having some edgy new
user interface, or by a gimmick around disappearing messages, but
by providing real value, value that can be measured in the
pocketbook of a market that is massively under served.
So the next time you are thinking about “putting a dent in the
universe”, maybe you should look a bit farther, and maybe, just
maybe you should start with a J2ME app.
