i have seen much more valuable posts that do not even get noticed.

But you do recognize that's a subjective opinion, right? "Value" is something the community is still defining, especially the whales. From their perspective, promoting anyone with a large following is probably a good business decision. The more eyes on steemit, the better. As to the long-term influence of this specific post, it's hard to say. I know Steemit got my wife into crypto after three years of me failing to do so. That gives me hope.
