Mr Jacobs is an academic and the reality of Zulu Wikipedia is that only a few days ago we celebrated article number 1000 for the Zulu Wikipedia. What the Zulu Wikipedia needs is high school students writing in Zulu. Writing about what is important to them, what is important to their curriculum and to their world.
Just consider what one high school could do. Now consider what ten high schools could do. Compare that with one academic or what all the Zulu students currently in university could do.
Yes, history has been written so far and it does report in a biased way. When the Zulu language is to gain a foothold in the Wikimedia world, we need many people being involved in writing first the most basic information. Once there is a basis, the sources Mr Jacobs mentions become relevant in a Zulu Wikipedia.
