Every day thousands of articles are created, and many of those are not added to Wikidata, even while often an item about this subject exists. Users forget to add a newly created article to Wikidata as there is no stimulus at all. The next step in Wikidata development is that after the creation of an article, users get a message (pop-up, or screen, etc) in what they are asked to add the article/category to Wikidata. In the first stage this can be just a pop-up with a message. But it would be better if this can be a message + some help to do this, so that users can stay in Wikipedia (or another project), without having to go to Wikidata.
