Facebook founder Mark Zuckerberg is back in Nigeria and he will be one of the judges at the finals of Aso Villa Day taking place at Abuja. Aso Villa Demo Day is a programme that aims to promote entrepreneurship, innovation and economic growth through new and emerging technology. Mark Zuckerberg earlier visited the Presidential Villa, Abuja and met with President Buhari and VP Prof. Yemi Osinbajo donning a sharp looking suit. When VP Osinbajo asked him Mark why he wasn’t wearing his ‘traditional’ t-shirt &jeans, he said it was out of respect for the formality of meeting a President.
