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.
