Well that question only makes sense for connected graphs, we don't really know whether this is connected. So in general a version of this question that makes sense is, among all the connected components of the wikipedia graph, what is the largest diameter.

This is great. It's essentially asking you to work in a 2-category[1], which, once you get used to it, is an amazingly intuitive way to make sense of constructions in ordinary 1-categories.
