Wikipedia

Wikipedia is a collaboratively edited, multilingual, free Internet encyclopedia that is supported by the non-profit Wikimedia Foundation. Volunteers worldwide collaboratively write Wikipedia's 30 million articles in 287 languages, including over 4.4 million in the English Wikipedia. Anyone who can access the site can edit almost any of its articles, which on the Internet comprise the largest and most popular general reference work, ranking sixth globally among all websites on Alexa with an estimated 365 million readers.

Goteo

Platform for crowdfunding or collective financing (monetary contributions) and distributed collaboration (services, infrastructures, microtasks) for projects which, apart from giving individual rewards, also generate a collective return through fomenting the commons, open code and/or free knowledge. As a member of the network you can have one or various roles: presenting a project, cofunding or collaborating on one.

Open Street Maps

OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. Two major driving forces behind the establishment and growth of OSM have been restrictions on use or availability of map information across much of the world and the advent of inexpensive portable satellite navigation devices.
