johanneswilm writes "While writing my Ph.D in anthropology I found out it's almost impossible to get non-geeks to help me with editing my thesis because it was written in Latex. Lyx is almost there, but as it's not web based, it's difficult to use for online collaboration. Writelatex.com is online, but typing LaTeX code is a no-go for non-geeks. Google Docs is web based and near-WYSIWYG, but lacks support for professional print formats such as Latex. The Ph.D took longer than expected, so before finishing me and three others were able to code an entirely new editor: Fidus Writer: web based, open source (AGPL), almost-WYSIWYG and with tools for academics such as citation management and formula support and output formats PDF, Epub, Latex, HTML."
