#Wikipedia has its red links and following this great example, Reasonator has its red lines.
A Wikipedia red link suggests that there is room for another article. Wikidata already knows much about the missing information, to do this it falls back to whatever fall back language is indicated and ultimately it falls back to English. All this to share in the sum of all knowledge.
What is missing is a label. As you may know Reasonator operates in any language. By red lining a label, it is suggested to add a label in the selected language. Once this label has been added to Wikidata, it will be used everywhere where an item is used.
Now consider that we replace Wikipedia red links with the information served up by Reasonator... Don't you think it is a big step up from serving nothing at all?
