What exactly is the article booster? I understand that it’s where people improve new articles, but is it where the quality review notice is removed and the article is published into a stub or a normal article?
More than that. If an article is submitted and the NAB team doesn’t consider it up to par with standards, it’s demoted until it can be improved. If it’s ever improved, that’s when it’s promoted and goes live. It used to be that articles went live immediately upon the click of the ‘Publish’ button, meaning essentially the reviews were done on live articles. Thankfully the “Hatchery system” (what this is called) has since helped improve wikiHow’s image!
