It's worse than that. Since you can't editorialize titles and some authors like to give their articles poetic, meaningless names like "A butterfly in the sky," when the actual article talks about a security exploit in Bitcoin, coded in Go and released by Wikileaks.
I often find myself ignoring interesting articles on HN only to go read them later on reddit with a much more descriptive, editorialized headline.
Right now there's a good example of this problem on the front page. The article about the Android/PRNG security flaw is aptly editorialized as "Google confirms Java and OpenSSL crypto PRNG on Android are broken," but the original article is titled "Some SecureRandom Thoughts," which is meaningless and I would never have clicked it under any circumstances. Thankfully the mods left this one alone.
