If I could offer some advice to people who use #Markdown
to write posts:
Many people use Markdown not just because the formatting is convenient to write, but also because it is itself human-readable. Consequently, it's also used as a plain text alternative to e.g. HTML-rendered text. I read a lot of things in plain text, so I see plain Markdown frequently.
One of the worst things you can do for legibility is to place URLs inline---it obscures the text, especially if there's a lot of them. Instead, use a reference (ideally numeric), of the form "[foo][n]".
Then, rather than placing all URLs at the bottom of the document, please them below the paragraph that references them. Not only does this reduce scrolling, but it also allows easily copying/pasting portions of the text while keeping the references intact, which is especially convenient for quoting.
