As the author of the article, I hope it's clear that we're talking about the community that has formed around the programming language. Racial diversity isn't, to the best of my knowledge, mentioned at all in the Haskell Report or the source code to the GHC compiler. But when I'm talking about the community, that is all about the people in that community. Some of the people in that community have very different backgrounds from myself, and I think that's a valuable thing to celebrate and acknowledge. That said, it wasn't the point of the article. It's fast becoming the point of this comment thread, though, which is unfortunate.
