Since its first emergence in 2001, Wikipedia had grown drastically to become the fifth most viewed website over the Internet in 2012. With over 12,000,000 articles in more than 250 languages this is now the largest source of information ever existed. The Wikimedia foundation has been founded in 2003 as a non-profit organization to support Wikipedia as well as other online and offline free content projects.
In this talk I will present Wikipedia and other projects of the Wikimedia foundation and how they work. I will show how one can become a Wikipedia editor and why would she want to do so. We will talk about readers, editors, Neutrality, reliability, dispute resolution, style and free content.
