Right - Betteridge's Law does not apply very well. My point was more that an article that presents an open question is interesting food for thought - as opposed to articles devoid of substance that seek to answer everything in their headline. Now that you know the term, look in the comments every time you see a '?' on the front page, and you'll see the law mentioned. It is not a claim to be smart, as the peer claims, it is an indication that I spend too much time on HN.
