If the title "Why I prefer rST to markdown" (which a 100% accurate summary of the content) is somehow "clickbait", then the term "clickbait" has been redefined into meaningless.
Since it's a clearer statement of the author's meaning, and since very few users interested in Markdown are going to be doing any typesetting, it seems like a more meaningful title to me.
But less likely to draw in readers... to "bait" them, if you will.
