"where he was too afraid to put it on HN"
Hard to believe he was "afraid". More likely simply a gimmick to make it stand out (not implying negative by use of that word).
Besides I don't get this:
"My boyfriend Mark is way too much of a perfectionist to post his startup on HN"
He posted his startup on HN that is "marknadal" posted the link to his girlfriends video.
And what does being a perfectionist have to do with this anyway?
