> But this indeed asks the question, which as far as I can tell is completely unaddressed on their website: why create a group that excludes others by sex and race?

Or any 14-year-old whose parents are below the poverty line, who also wants to learn to code? You read Hacker News. Surely you understand the importance of focus to any endeavor. The same principle applies here as to a startup — it's easier to sell "Twitter for internal business teams" than "this is an app that, like, helps people communicate and stuff in various ways."
