South Africa is one of the more challenging places to get to from Asia or North America. And costly.
Worse, There is not a single flight on the planet from North America or Asia to Cape Town, you'd have to fly in to Johannesburg (and there are only 2 flights from the East Coast that even go there).
I'm not suggesting conferences have to pick a venue in North America or Europe for an event, but open source conferences often have more budget-conscious attendees and I imagine picking a venue with many more travel options and less hours in the air would be far more cost effective to reach. :-)
Hosting open source events in places like Nicaragua and South Africa is a great way to introduce more people to the community, that otherwise would be very difficult for them to join.
