When you are in the public sphere you do not spew out every thought that comes out unfiltered - whether it is trump or musk it damages what they stand for and works against them.
I would expect a president, 3 years in, to be able to communicate to all his constituents with a measure of forethought and attempt to keep in mind that not all of them apply "critical thought".
Personally I prefer explicit markup attributes. i.e. if I want to mark something as code an markup like ``` or {code} or whatever is clearer than inferring tabs for code formatting, this kind of accidental code blocks could be easily avoided.
On a side note I read on mobile all the time, I understand the frustration, but it not poster's fault HN has some poor formatting choices which are not mobile friendly and no preview options, you should direct their feedback towards HN rather than the poster, most of them do not do this intentionally.
If you want to make a list, there’s nothing wrong with using new lines, they will work just fine.
A code block however stimulates rage.
