> long URLs interrupt the text just because you want a hyperlink
This annoyed me until I realized pandoc supports separating [the link text] from the link location.
[the link text]: </url/to/resource>
"`title` parameter of the <a> tag, if converted to HTML"
Yep, but (a) that isn’t portable Markdown, (b) your editor probably doesn’t support opening the link from the link text in that case, and (c) whenever you want to modify the link text you have to modify all occurrences. A word processor can handle that automatically for you. It can also offer completion (like tab completion) for references that you use repeatedly. It can show as a tooltip what a given link text links to. Conveniences like that is what computers are for, let’s not relapse to the stone age here.
