can you face the #100wikidays challenge on Wikidata? It's aptly named #100wikidatadays. It is a personal challenge in which a person very significantly improves (at least) one Wikidata items per day, for 100 days in a row. There was already a version of the challenge on various Wikipedias, on Commons and on Wikisource - now on Wikidata as well. Participate and make Wikidata shine!
