Why is the cropped title HN's fault?

HN auto edits some clickbaity/tropey titles in submissions.

Submitters have a grace period of several minutes to edit them back to anything they want, which will not get autocorrected, but many fail don't. They may not realize it or be too lazy to care, we'll never know. (Personally, I think anyone who considers themselves a "hacker" would at least try to bypass such a primitive system, but I digress...)

Some HNers complain every time that happens, gleefully oblivious to the countless other times the autoedit feature works as advertised.

Probably because "The best X" is generally clickbaity.
