In my head there are corrections that are rude that I don't do, because I genuinely think authentic writing matters more and more, and because I am absolutely not above reproach where grammar and spelling is concerned.
Then there are things I think people would want to know, that are either in the intellectual-you-have-a-little-bit-of-pinach-in-your-teeth territory or in the "cool fact" territory, or somewhere hazy in between.
I figured if one is going to correctly use an expressive phrase like "bury the lede" that they've perhaps only ever heard someone say, they would absolutely want to know about the spelling quirk, because it fully makes it better.
Other people obviously read it differently and the downvote was a useful signal.
Since "lead" (as in beginning of a story) and "lead" (as in metal) were frequently used in print newsrooms, the spelling of one changed over time to reduce confusion.
There were a number of other language convolutions in newsrooms, such as "slug" which meant a piece of hot metal, and so was useful for describing a spent bullet, the very short text that served as a title for a particular story, and a section of metal letters on the printing press.
/Worked for two major newspaper companies back when printing newspapers was akin to printing money.
When the story was complete, the notification varied from newspaper to newspaper, but very often they followed the AP's convention of writing "-30-" which I have always believed was something the AP print wire actually (and surprisingly) adopted from the broadcast side, because broadcast stories were ideally 30 seconds long.
