On average there is little or no support for subjects that have to do with Africa. When I check the articles for politicians for instance, I find that even current presidents let alone ministers are missing in African Wikipedias. So it is wonderful that there have been projects that deal with gaps but what if there is hardly anything?
What this approach brings us is at least information. Basic information in lists, info boxes maybe an additional line of text.
What we apparently have not done is learn from the Cebuano experience. The biggest issue was not the quality of the new information, it is the integration with Wikidata. Everything is new and it did not link with what we already knew. What we bring in this way is integrated information and as long as data is not saved as an article, the quality provided improves as Wikidata gains better intel.
If anything, the experience of the Welsh Wikipedia brings us more than gapfinder or tiger editathon because of this is more in line with this approach.
