The best open source projects

Ana Kronschnabl and Tomas Rawlings pick the best open source websites where users can change the content.

Here is a sneak preview of the list;

Wikipedia

www.wikipedia.org

Wikipedia is an online encyclopedia of more than 2.3 million articles in 180 languages. It is currently the most used reference site on the internet. What makes it all the more startling is that the site is built by and maintained by its volunteer readers. Anyone who uses the site can easily and quickly update the content on any entry. This has created one of the most vibrant, informative and accessible information systems in the history of human knowledge.

Firefox

www.mozilla.org/products/firefox

A web browser is the software you use to view a website. Most people use Microsoft's Internet Explorer, but it has been criticised for security flaws. There is an alternative; Firefox is an innovative piece of software created by a handful of people working in a non-profit foundation, but incorporating internet experience from users all over the globe. Their efforts have successfully created the main rival to the megabucks Microsoft - and it's free and easy to use.

The other projects are;
Open Office, Bittorrent, MediaWiki, Xvid, pbb, Outfoxed, dyne:bolic, GIMP, Apache and SourceForge.
