This is the Wikidata summary of the week before 2018-02-19.

The weekly newsletter was started by Lydia at the very beginning of the Wikidata project, even before the first deployment, to keep the community informed about the developments, the new projects and tools. More than five years later, the newsletter is still there, its content powered by the community, and sent every week all along the years. I wanted to say a warm "thank you!" to each person who helped filling the Weekly Summary <3

Over the past years, as you know, Wikidata has grown a lot. More data, more tools, more editors and reusers, more exciting projects led by the community. The Weekly Summary has evolved with us, and the 300th edition seems a good moment to ask you all your suggestions about the newsletter, how it could continue evolving, and how you would like to improve it.

On that purpose, you can find a feedback page to express all your ideas about the Weekly Summary. We're very interested to know more about your reading habits, the parts you're more or less interested in, the new topics you would like to share with the community. Thanks in advance for filling it.

I stay available anytime to discuss with you, feel free to contact me if you have any question or concern! Cheers, Léa
