A commentator on Arslan's post mentions “Medium’s foolproof wysiwyg editor.” This surprised me. I find their WYSIWYG editor to be incredibly frustrating, counter-intuitive, limiting, and obnoxious.
Allow me to belabor only the last point.
Imagine typing the following sentence (I’m using pipe | to show the cursor):
Clifford is a big dog.
But it's missing something, so you move your insertion point:
Clifford is a big| dog.
and you type “red.” In any sane editor, the result will be exactly what you typed:
Clifford is a big red| dog.
But on Medium, the result is:
Clifford is a big red|dog.
Clifford is a big reddog? Ffffff. This happened because when you typed the first space after “big”, the result was not the insertion of a space but in fact the same as if you had hit the "right arrow" key:
Clifford is a big |dog.
Not cool. I have a strong habit of inserting words with the surrounding spaces already inserted. How dare Medium forbid me to type the way I want?
I know that Medium does this because they are on a crusade to kill the usage of two spaces after sentence. That doesn’t excuse insane frustration of the editing process. No wonder most Medium posts don't look like they have ever experienced the most cursory proofreading!
