Nigeria: Social Media and Development - Uses and Impact?

We all know about the growth of digital in Nigeria. And within that growth there are trends of course - I was intrigued by this article related to business - Nigeria: 2016’s Biggest Social Media Trends for Business. But how effective have we all been at harnessing those digital trends relative to Development goals, no matter what those goals may be, from peace and security through the full spectrum of democracy and governance, education, gender rights, community advancement, health and much more to something as specific as polio eradication? Three questions for your response and sharing in support of all engaged in Development action in Nigeria (a) please provide a brief insight into some good examples, in your opinion, where digital media processes have been applied to a Development priority (b) how do you assess the impact of digital growth in Nigeria on key Development goals and (c) where are the present opportunities to harness digital in an improved mannner for Development progress? Thanks
