Woah, this is a wild claim. @dang: Is this a thing? I don't believe it. I, myself, have submitted many articles and never once did I see some auto-magical "title shortening algorithm" at work!
I went to check if this was documented in the list of undocumented HN features on GitHub but it’s not.
There is an open PR (by simonw btw): https://github.com/minimaxir/hacker-news-undocumented/pull/4...
