Unrelated to the content of the article, what's up with censoring "wtf" in the title? I often see links with "WTF" (usually in caps) in the title, so I don't think this is coming from the HN side. Is this an edit by the submitter? This makes it a bit hard to understand what is the article about. Or is "wtf" not okay now? I've never lived in America so it's hard to understand what's okay and what's not around swearing.
