Openness is central to MDN, in that anyone can create an account to edit the content, and anyone can copy and reuse the content, under its Creative Commons (Attribution‐Share‐Alike) license. Likewise, anyone can join in discussions about planning and task management, via publicly accessible tools. This openness has coalesced a community of volunteer contributors that extends far beyond the small staff who keep pace with the rapid release cycle of Mozilla’s flagship browser. The online collaboration also manifests in face‐to‐face events such as monthly MDN‐focused meet‐ups in Mozilla’s London and Paris offices (joined by a video conference link), and other ad‐hoc gatherings that members may take initiative to throw.
Currently, MDN has over 4 million users per month and more than 1000 volunteer editors per month, worldwide. In July 2015, MDN will celebrate its 10th anniversary, as the original MDN wiki site launched on 23 July, 2005.

2005: Mozilla obtained a license from AOL to use content from Netscape’s DevEdge site. The DevEdge content was mined for still‐useful material, which was then migrated by volunteers into a wiki so it would be easier to update and maintain. The new wiki was launched in July 2005 as Mozilla Developer Center (MDC), also known as “devmo,” shorthand for its domain name, “developer.mozilla.org.”
2010: The name was changed to Mozilla Developer Network (MDN), reflecting the site’s growth into a nexus for all developer documentation related to the Mozilla Project and open web technologies.
2011: A “Demo Studio” section was added for web developers to share and show off their code, along with learning pages to provide links to tutorials.
2014: The basic learning pages have been expanded into “Learn the Web” content for beginning web developers, including a web terminology glossary, which Mozilla staff and volunteers will continue to develop over the next few years.
