Well I'm disappointed to not see a bunch more people promoting their local tech hubs, dev communities and such if they have them. Zambia has the people over at -> http://bongohive.co.zm and a few more that aren't involved with that hub.

I know I have many "dark matter" programmers as friends. A lot of Africa in my experience as tribaal pointed out has a great many hurdles that need to be overcome in order to be a programmer. For example I have to pay the same price he does for internet access, US$60 and it's only a 512k line. Worse, service has been so bad lately I'm lucky to have more than an hour of stable uptime at a time at an average of 10kb/s.
