Since FOSDEM brings many European open software developers to Brussels, it also provides an important networking opportunity. FOSDEM traditionally kicks off Belgium-style on Friday with a beer event, but during the entire weekend several groups hold parties all over town. Wikinews reporters attended a barbecue hosted by the Electronic Frontier Foundation (EFF) on Friday for an interview with EFF and Open Rights Group representatives about the upcoming E.U. proposal to extend copyright for performers to 95 years. Wikinews also interviewed Drupal founder and Acquia CTO Dries Buytaert about Drupal and how Acquia will relate to the Drupal developer community.

During the conference weekend, presentations touched on programming languages, build systems, gaming (such as Battle for Wesnoth, Crystal Space, Globulation 2), packaging, virtualisation and web applications. The conference also has rooms (called DevRooms) were developers who usually work together via the internet can meet in real life and share thoughts on their projects; CentOS, Fedora, CrossDesktop, Drupal, GNOME, KDE, Mozilla, OpenSUSE and X.org had the biggest rooms this year. The corridors were filled with stands from organisations such as the Free Software Foundation Europe and the Free Knowledge Foundation, Debian, Ubuntu, OpenOffice.org, etc.
