For many editors, DYK is a key step in producing an article. For people trying to work their way up into getting featured content, it often follows an "article creation, DYK, GA, FA" pattern. Some editors get a nomination for every single article they make, and nominate others' articles. Medals are occasionally awarded for getting 25, 50, 100 DYK credits and if your page gets more than five thousand views with its stint on the main page it will be added to the stats page. A prestigious project indeed.
So I wondered, why then, have we not covered this before? A quick look down our archive (have a go yourself) shows not a mention. It is referred to multiple times in other reports; yet has never had a full-length feature to itself. Many of the people working regularly at DYK now can show us what we've been missing.
