There's a HN auto filter that removes unnecessary words from titles

That could be the cause

[okamiueru]

Expressions like "huge deal", should perhaps be left alone. Either that, or replace both with "significant" or "important". But that too seems silly.

Perhaps? It completely changes the original meaning.

This are the weird and visible cases of HN's title rewriting algorithm going wrong.

I guess the cases where it does the right thing are not noticeable, and that's why I only see the bad cases. Are there examples where HN title rewriting did something good, or cases where before HN did this titles were very bad or clickbaity?

Thanks! (Including the descendant commenters.)

Wondering about that is why I bothered to comment at all. I assumed there must be some logical-but-not-quite-working reason. :-D
