My company has decided to standardized on phone numbers with dots instead of dashes. They’re in email signatures, memos, client proposals. I absolutely hate it and it rubs me the wrong way every time I see it. It’s wrong.
Although I actually like that format a lot, we use characters to help elicit context. 2023/08/09 is fine since we have been using / for dates for so long. Also it blows my mind why people don’t use : in 24 hour times. 16:40 is great, no am pm bullshit and you immediately know I’m talking time.
