Of all African countries, the following are worth looking at: South Africa, Cameroon, Ghana, Morocco. Maybe Senegal, they are politically stable but not sure about internet penetration there. Then maybe .cd (Congo) is interesting only because CD is a common term pretty much like FM or TV, the issue is that Congo isn't the most stable place on the continent.
Ghana, Cameroon, Morocco and South Africa have rapidly growing economies AND relative political stability.
In the rest of Africa there is either lack of internet penetration or lack of stability to consider the other ccTLD's already for investment. Maybe once the situation became politically calm, Ivory Coast and Nigeria and such would be safe bets too. But for now, the only countries where I see economic growth, growth of internet users, AND without political unrest, are S.Africa, Morocco, Ghana and Cameroon.
