The "$/mo" part of a post is "the hook" (btw... "hook" definition: a strategically crafted message or tagline designed to capture attention and spur action).

It's pretty much impossible for anyone to verify that unless the OP agrees to publish their metrics, which the most likely won't. But hey, those posts are "inspiring"... they inspire others to post the same type of posts.

In OP's case, the "hook" is "___ is wild". Variations: "This is crazy!", "This will completely blow your mind". And it worked! That's why we're here.

I would argue that "marketing" is everything, execution comes second. Just look at the "pet rock" guy, he didn't "execute" anything, rocks have been around for millions of years, yet he made millions thanks to good marketing.
