Facebook has over 100M MAUs in Africa

"Facebook just keeps on growing. The number of people accessing its social network each month has reached 100 million in Africa, further highlighting the opportunity for expansion through emerging markets.
According to Facebook, more than 80 percent of its monthly active users in Africa are now accessing the platform from a mobile device. That’s a high attachment rate for feature phones, smartphones and tablets, suggesting usage on laptops and desktop PCs is slowly being left in the dust."
