Users of Blackboard Collaborate
I would use it and promote Open Source software, specifically Moodle to African nations.
Why? I look at the clustrmaps.com map of web visitors on my Moodle site (http://scm.moodleace.com)
Then at my blog (http://moodurian.blogspot.com)
Again, I notice NO visitors from the continent of Africa (- yet!).
I know that there ARE Moodlers from Africa, so the graphics above do not show the real picture.
Nevertheless, I would use the virtual classroom to achieve this vision:
To achieve this vision, as a practical step,
I'd help to organise a mini-Moodle MOOT for Africa, bringing together the best Moodlers of africa together to donate their time, talents and skills to showcase their use of Moodle in their current institutions, to a continental audience of African users.
The free Blackboad Collaborate room will come in very handy as a vehicle and platform for such virtual teaching to that target audience.
So that's what I intend to do to make this world a better place.
