I didn't know about this HF20 change, thanks for telling.
That makes Steem more like Medium indeed and you can get continuous SEO by improving your old articles frequently also.
And getting back to the quality of my post. Maybe you find it poor quality and I accept you opinion, but a lot steemians also found it interesting and even started following me.
So, quality is subjective for everyone and for now I think more people enjoyed my update. And I'm grateful for promotion bots to allow me reaching more steemians.
