It appears that the actual title of the article is "Hobbies are not distractions", with the HN submission title being... I'm not sure it's really a subtitle, maybe a pull-out point from the quoted reference in the article?
[Edit: though, since it looks like the author wrote both the article and the HN submission, this point might be somewhat irrelevant.] :-)
Thanks. I have sucktastic eyesight and only skimmed a bit.
So this is also a pointless violation of HN guidelines, which indicate you should use the original title unless it's clickbait or a few other provisos.
Of course, "the first rule of downvotes is don't talk about the downvotes", but I've been genuinely puzzled by why this particular comment has so many downvotes. And I think it's because the title was changed at some point, apparently without a note being left anywhere indicating that. It didn't originally have the part about "compared to their peers".
