Hello all, This it, the fourth anniversary of Wikidata! I'd like to say thank you to all the people who make this project awesome. Each one of you, all the people building cool tools for and reusing Wikidata data, and of course our development team working very carefully to improve our favorite collaborative knowledge base. - Let's start this birthday week with *a word from the development team <https://www.wikidata.org/wiki/Wikidata:Fourth_Birthday>* (thanks *Lydia* and all the reviewers). - Inside you will also find a new version of *the map showing all the Wikidata items <https://www.wikidata.org/wiki/File:Wikidata_Map_October_2016_Small.png>* with geolocalisation, made by Addshore, who explains how he generated it *in a blog post <https://addshore.com/2016/10/wikidata-map-october-2016/>*. - Also thank you very much Charlie for the very nice *birthday logo* <https://commons.wikimedia.org/wiki/File:Logo_fourth_Wikidata_Birthday.png> :) And now, let's celebrate! Feel free to let a message on the bottom of |the birthday page <https://www.wikidata.org/wiki/Wikidata:Fourth_Birthday>, tweet with #Wikidatabirthday, or attend to an event (next ones tonight in Paris <https://fr.wikipedia.org/wiki/Wikip%C3%A9dia:AG_2016/Soir%C3%A9e> and Utrecht <https://nl.wikimedia.org/wiki/WikiZaterdag#29_oktober_2016>).
