Wikipedia is meant to be "the free encyclopædia that anyone can edit". We know from research, however, that most people can't edit, and so we, a team from the Wikimedia Foundation and Wikia, are building a visual editor to bridge the gap. This is particularly challenging because MediaWiki's syntax, "wikitext", is a significant superset of HTML, and Wikipedia's content is so complex, using every possible form of it.
VisualEditor is now the default way people edit Wikipedia. We have provided a simple way to create and edit articles, from tiny stubs to mature and complex articles, in any of the 300 languages we support, while still allowing experienced editors to use the old wikitext editor if they want to. With an eye to the future, we have also been carefully preparing the way for the later addition of real-time collaborative editing.
We will talk about and show off the work we've done, the decisions we made, and the issues we worry about. We will ask you what you think, how you might use it, and what more we can do to make VisualEditor the best HTML editor on the Web, whilst making editing Wikipedia -- and all our wikis -- truly open to everyone.
