Being viral, for content, is not always bad: it can make an otherwise boring or tedious subject engaging and enjoyable (and on the other side, a fun subject might appear boring if badly written), which I think is what this article is about :-).
But I had never heard of using that same trick to solve puzzles where you find how two pictures differ. And I tried it out and it worked for me.
It took something I had limited application for and turned it into a slightly less limited power. And a great party trick. That’s sort of a superpower :D
In this case though, it's a dude posting on his own blog. I'm fine with whatever title he found cool.
