The low barrier to entry and segregation of
content from technology implementation allows publishers to concentrate on their
core competence and stay ahead of the game for their
respective audiences.
Korea's Kakao Talk and China's WeChat — both of which dominate their
respective domestic markets and are pushing out internationally — follow a similar approach, but, perhaps more telling, is that Tango, Kik and even BlackBerry's BBM, three WhatsApp rivals with a
core audience in the US, also include gaming and other
content.
