> There's a good reason that when you look at successful start ups they're generally founded by people who have experience in the customer base that they're building their product for. I have no trouble believing this, but I don't think this transfers to the OP. Facebook is not a startup anymore, and end users are not even Facebook's direct customers (they sell ads, not accounts). But more tellingly, why stop at race (and other protected classes)? Why not optimize for the right balance of first spoken language, political party affiliation, age, family net worth, educational background, number of children? I think we're overanalyzing what is essentially a fluffy slogan from a person whose sole job it is to widen Facebook's candidate pool.
