What is common knowledge in your field but shocks outsiders?

More than half the CO₂ emissions of the industrial age have been dumped into the atmosphere since 1990.

@davidho Bleeding is stanched, not staunched; two spaces after a period is now passé—one is correct; editors accept manuscripts with with errors and typos all the time—it’s the quality of the writing that counts.
@davidho Haha, and they also make mistakes, especially when preaching about typos. I used to accidentally call myself an ediotr, which seems very apt!

@thelmadonna @davidho That's Muphry's Law.

I was pleased to find the phenomenon has a name.

@thelmadonna I know one person who still uses two spaces after a period, and I found that out two weeks ago. That was shocking.
@Sumocat Here’s a deeper dive on the issue of spacing after a period: https://cmosshoptalk.com/2020/03/24/one-space-or-two/ Editors will not reject a manuscript based on whether or not the writer has conformed to house style, which pretty much always specs a single space after a period, but they may go ahead and just change it. 🤓
One Space or Two?

It hasn’t reflected publishing standards since the Jazz Age. And it isn’t Chicago style. But some people continue to do it in their own documents—from manuscripts to emails. You’ll even see it occasionally on social media.

@thelmadonna @davidho Being a teacher of Spanish, such nuisances of English writing annoy me, not only because English is not my native language, but because for DECADES grammar checking tools for Spanish were written by English-speaking people that did not know punctuation rules differ between languages.
In Spanish, dot comes after quotes, a single space comes after dot, and the em-dash come in pairs, —this way—, with spaces before the first and after the second.

@thelmadonna @davidho

> one is correct;

It turns out that, astonishingly, one is permitted to use any number of spaces after a period and no one can stop you, and no one corrects you either way.

I moved from two to one and then back to two and not one person ever commented or cared, including editors.

(I moved back to two when I started adding more whitespace in general, because my eyesight is slowly deteriorating.)

Study: Two Spaces After a Period May Be Better Than One

A new study proves that half of people are correct. The other is also correct.

Nah, two spaces after a sentence is good. I like the clarity.
