If the Foundation wanted to enquire, or do something about the relative dearth of African American editors, a good person to contact would probably be Henry Louis Gates
http://en.wikipedia.org/wiki/Henry_Louis_Gates
He's a Harvard professor, famous for having been arrested on the front porch of his own house by a white policeman who thought he was a burglar. More saliently, he is noted as the author of
Africana: The Encyclopedia of the African and African American Experience
He also co-founded The Root, an African American online magazine
There are lots of search hits for Wikipedia on theroot.com, so it's not like black people don't read it.

The Root is open to broad public participation. And has an active comment section attached to their articles, a good opportunity to add your comment and relate the topic to the Wikipedia article on the subject, see for example:
