My online research skills aren't great. However, I spent the last 10 minutes trying to find out who are the owners of the site and was not successful.
The owners could be Black but my personal experience is that Black people who have Black culture related sites make it known. They should, they want the community to know they have a site that serves them from one of their own. Including this one.
My experience is that non Black people or even Black people who aren't tied strongly to the black American community stay off the radar by on purpose.
The Source, And1 are owned by Whites. They made sure they stayed in the cut behind the scenes.
My guess its the same with The Coli. I could be wrong, but I wouldn't be surprised if it was non Black owned.
