From SXSW panel:
Jeanne Sessum who writes allied.blogspot.com and asked “How white is your blog roll” and bloggers where shocked because they had either not considered it or that the blog roll is all white. Your blog roll is a reflection of what you see day to day in your life. People link to the people they see and the voices they reflect as valid voices. If you are a white man who only respects white voices. Your blogroll will look like you. Same for black bloggers.
