Wikimedia Foundation annual report 2010–11


November 2011

Back in January 2001, few people could have imagined the extraordinary impact of what was then just a tiny project driven by a big idea.

But ten years later, we find ourselves at the center of a free knowledge movement built around our flagship project, Wikipedia, which has become the most important collaboratively created repository of knowledge in history.

Today, Wikimedia volunteers around the world work in more than 280 languages to document the stories of their communities and cultures, past and present. During 2011, for example, hundreds of volunteers contributed to the articles on the Arab Spring rebellions, capturing one of the major stories of our time as it unfolded.

The Wikimedia Foundation is part of a broad global network of individuals, organizations, chapters, clubs and communities who together work to create Wikipedia, the most powerful example of volunteer collaboration and open content sharing in the world today. In 2010–11, the bulk of the Foundation’s spending was focused towards putting in place solid technical and organizational infrastructure. In 2011–12, the majority of spending goes towards growing, strengthening and increasing the diversity of the editing community, simplifying our wiki-editing interface, making investments to grow the projects’ readers and editors in key geographic areas such as India, Brazil and the Middle East and North Africa, and improving our presence on mobile devices.

Over the past year, more than 500,000 people donated to the Wikimedia Foundation, giving us more than $23 million USD. Thank you for your incredible generosity, and for your outpouring of support and love for Wikipedia and its sister projects, enabling the work of nearly 100,000 active editors. We owe you a huge debt of gratitude.

The Wikimedia Foundation especially wants to thank the editing community. Your work is essential, and it is what donors are enjoying and supporting: thank you for everything you do. A big thanks as well to the Wikimedia Foundation Board of Trustees and Advisory Board, and a warm welcome to our new Advisory Board members Veronique Kessler and Jessamyn West.

Wikimania 2010Edit

Wikimedians converge in the birthplace of Solidarność

The sixth annual Wikimania, the global conference of Wikimedians, took place in the Baltic Philharmonic in Gdańsk. Poland succeeded Argentina and Egypt, the hosting countries in the previous two years. During three days, Wikimedians got together to celebrate the free knowledge movement, to meet their collaborators in their year-round online work on Wikipedia and its sister projects, and to share insights informing the continuing evolution of the projects. Foundation travel scholarships enabled Wikimedians from 39 countries to participate.

On the conference T-shirts, the motto “Free Knowledge in the City of Freedom” tied Wikimedia values to the history of Gdańsk, where the Solidarność movement had defied communist rulers in the 1980s — led by Lech Wałęsa, who sent his greetings to Wikimania attendees, noting that he was a frequent user of Wikipedia.

The Polish Baltic F. Chopin Philharmonic in Gdańsk was founded in 1945 as the Gdańsk Symphony Orchestra. Its building on the Ołowianka island hosted Wikimania 2010.

Wikimedia chaptersEdit

During 2010–11, Wikimedia’s network of volunteer-driven international chapters grew from 30 to 35. Wikimedia’s chapters, which are independent from the Wikimedia Foundation, are made up of local members and directors, and in some cases employees. They focus on region-specific work. Typically, that work includes building awareness of Wikimedia projects, handling media inquiries, staging public outreach events, and forming partnerships with local educational and cultural organizations.
