while i am in favor to spend 150'000 cedi in ghana every year i would love to see contributions encouraged, be it content, software or openstreetmap. there were a couple of beautiful efforts on english wikipedia, on commons, as well on akan wikipedia like malaria:
beside the cost of internet, mobile editing is crappy enough that it blocks new editors. sit in a university and ask 500 persons to edit an article is much more worthwile imo than ask 20 existing editors why they do not edit so much as they could. then we could open phabricator tickets
https://phabricator.wikimedia.org/ to get this fixed.
