"I am deeply grateful to our donors," said Sue Gardner, executive director of the Wikimedia Foundation.
"Most of them are not rich. They are students and teachers and parents -- people who use Wikipedia regularly, and people who are willing to help pay to keep it going. Their generosity is what keeps Wikipedia available for people around the world, free of charge and free of advertising," she added.
The corresponding campaign in 2008/2009, raised $US6 million from 105,000 donors. Although the average donation fell, that was more than compensated by the greater number of donors to the latest campaign.
The foundation intends to spend the money on people (it has a staff of 33) and on servers, bandwidth and other technology costs including contractors.
