Wikimedia Deutschland wants to help ensure that Wikipedia & Co. continue to be fun to use. That’s why we regularly ask contributors about the most important missing features or those in the most need of improvement. After the community discusses and prioritizes its “technical wishes”, the team at Wikimedia Deutschland then determines which ones were feasible – it then implements them. The year 2016 was an incredibly productive year for the project, for many technical innovations could be realized. One major success was the release of the “RevisionSlider”, which makes it possible to navigate between the different versions of an article. Collectively developed tools like this one or the similarly jointly developed analysis tool, which shows the number of views of Wikipedia articles, are subsequently made available to Wikimedia projects in all languages. The collaborative nature of the “Technical Wishlist” project supports the common production of open knowledge.
