In org you don't need to remember. You just `C-c C-l` and it interactively asks for a link. You can type it or paste the link from your clipboard. _Then_ it asks you for an optional description.
The same command works if you want to edit a link under the cursor.
Also, most people have `C-c l` bound to a function that “captures” the link from wherever you are in Emacs (e.g. a newsfeed, a document, an email, a folder) so you can easily reference those places from within Org.
I think we should either compare these languages in a plain text editing context, or when used with editors with support for the syntax. Anything else seems like an unfair comparison to me.
Because editors with MD support tend to have shortcuts for inserting a link or image too, so this isn't really an argument in favour of either syntax.
I agree with you. My intention was to perhaps highlight one of the ways that using Emacs can help someone be productive using markup (but as you pointed this is probably true of other editors with strong support for the language) and maybe help someone discover an important feature of the editor that they have missed.
