I disagree.
When I see the author's exaggeration and overconfidence, coupled with a lack of examples, I stop reading. It reminds me of driving by a paper mill. Memorable, yes, in the wrong sort of way. I'll remember to avoid it in the future.
I don't dig the writing. I find it uninteresting and unpersuasive. An author does not have to exaggerate to be interesting. Even a dry scientific article can punch you in the face. Isn't that interesting? Perhaps impact and exaggeration are inversely related. Perhaps become exaggeration is easy and overused.
There is a time and place for exaggeration, sure. However, a skilled writer has many varied tools: metaphor, details, humor, and much more.
There isn't one formula to good writing, certainly, but what I'm seeing here misses the mark.
