I think there’s also a generic way to format links such that anyone can click them from their own instance

Like this: /c/[email protected], won’t work when reading the comment on kbin, though, only on lemmy. For people too lazy to click on “view source” (or unaware of it): [<link text>](/c/<community>@<instance>)

Making that stuff easier and more intuitive is on the dev’s list and I apologise for anyone on a screen reader it’s symbol gore.
