There's now a free software portal on English Wikipedia: http://en.wikipedia.org/wiki/Portal:Free_software
Wikipedia has a lot of great articles about free software, but it also has gaps, and confusions about free software (and open source, GNU, Linux, copyleft, etc.) that are common in society are present in some corners of Wikipedia too.
The goals of the free software portal are to provide a starting point for people reading about free software, and to highlight areas where people who would like to contribute are needed. ...and the portal itself needs contributors and suggestions.
Free software portals on the French and German Wikipedia's have existed for a while: http://fr.wikipedia.org/wiki/Portail:Logiciels_libres http://de.wikipedia.org/wiki/Portal:Freie_Software
(The other languages are still waiting for someone to start one.)
Happy New Year's Parties!
