Be warned, either new reddit or the mobile apps (not sure which) deliberately insert extraneous slashes or underscores into links, so many links are broken when viewing on old reddit / need manual editing.

I'm pretty sure they're going to kill off old reddit, which will 100% certainly mark the end of my 15 years there.

New and old reddit use different markdown rendering engines. New reddit is able to handle the slashes introduced by the new reddit WYSIWYG editor, it also supports fenced code blocks.

Old reddit supports neither resulting in broken links and broken code blocks.
