#Wikidata? It must be the effect having a #Babel template has on your experience. It is how you set up the languages you want to see the labels for on a Wikidata page.
Not many people have this set up; currently there are only 1755 people have indicated they know English.
By adopting the possibility to import your Babel information from Wikidata, we hope that more people will set up their language preferences.
What we hope to achieve by keeping your language preferences in a cookie is that you will see more labels that you actually understand :)
