I noticed this at the bottom of a wikipedia page the other day — it’s a really great example of positive reinforcement at the end of reading an article. Imagine if news articles or topics had this.
First, it catches a lot of people with a real easy prompt: rate this. But it’s not just “did you like this article?” The four structured-data categories are useful. I’d can imagine someone rating “completeness” as a one or two stars and a second prompt being: “You rated the completeness of this article as low. What unanswered questions would you like a journalist to look into?”
But real key to this is the lower part asking for expert knowledge and the positive “ask” to help improve the page. I can see people who have knowledge of a subject visiting a page and thinking, “This part is so incomplete, so wrong” but then never doing anything about it. Instead, they go around to their friends trashing wikipedia. This little box at the end of the topic makes it easy for a knowledgeable person to not just click away without helping fix/improve the page.
Yes, the screengrab above is for the Muggle Quidditch page. Don’t laugh.
