teddyhHe should probably update his “About” page on his blog to remove ”I sign the DNSSEC root”, then.
If you're looking to correct people about random parts of their website, perhaps it'd be a better idea to mail them than to comment here, where they're never going to see it. What was the point of this comment, other than mean-spiritedness?
So you think I should e-mail somebody out of the blue, bothering them personally, to complain about their personal web site? Do you think that most people would react well if they recieved such a message?
HN is a quote well-known community. It is very common that people read the discussion on HN when their project or themselves are featured. And if they are that interested in what others think, they would then likely see comments such as mine. And if they are not the type to want to read comments, they won’t see my comment and therefore not be bothered by it.
I am baffled when trying to imagine why you think this is “mean-spirited”. On the contrary, this is the most respectful way to offer a minor suggestion that I can think of.
