Wikimania 2018 will be in Cape Town and a lot of words will be used to express the importance of adequate coverage of everything Africa. Words do not express the extend Africa is lacking in coverage. My estimate is that less than 1% of all humans known to Wikidata (ie all humans in all Wikipedias) is African. We cannot properly say where someone was born or died because we do not know all the places of Africa, we do not know its administrative divisions and we do not know its politicians. We have not properly structured the former countries and colonies of Africa.
We do not know really about Africa.
When one guy from the Netherlands can make a noticeable difference, it is obvious what two, three or one hundred people can do who care about Africa. In the Listeria list on several of my user pages, you find what are in effect watch lists about Africa. Every day I notice what changed about several aspects of Africa and regularly I add lists to it and become more aware how limited our coverage about Africa is.
It is 13 days to Wikimania and, you can make a difference by making a difference on the subjects I follow. You can add information, you can add even more Listeria lists. The biggest difference will be by relating all the loose ends and curating and refactoring what is wrong.
What is the point of a Wikimania in Africa when our coverage is at this level? Obviously, a call to make up for what we have not done so far.
