CNN "Blacks in America 4" : Blacks in Silicon Valley?

CNN's "Black in America 4" displays the difficulties of African-American entrepreneurs in Silicon Valley.  Some Black Silicon Valley enrepreneurs say there's plenty of evidence that active -- if often subconscious -- bias plays a role in their limited participation prospects.

Some ask: Where are the roots of the problem? Is it that venture capitalists shy away from funding minorities, or are there too few minorities entering the field? Others respond: The problem isn't that there are barriers, the problem is that Blacks aren't entering the field in the first place.  (CNN Money, 10/28/2011)
