Hoi,
Having read it, I find it is still very much a Wikipedia oriented.It makes use of the toolset by Markus. That is fine. the notion of diversity and notability is also very much culturally defined. It would be nice to know how the different wikipedias accept notability of people from other cultures and if it impacts the diversity of their own articles.
I have found that many people do not have an article in the languages of their own cultures. Often it has to do with an interest in a domain that is more of relevance to the other culture.
Diversity is very much part of a domain; in Roman Catholicism male dominance is obvious. I am curious if diversity in gender is affected by such considerations and if items with a single article are more in line with what is the norm for a culture, a domain.
