Group talk: LibrePlanet Gaming Collective
Some ideas off the top of my head:
http://lists.libreplanet.org/mailman/listinfo/libreplanet gives error "No such list libreplanet"
http://FreeGamer.BlogSpot.com is a nice blog about Free Software games.
http://LibreGameWiki.org is extensive and very concerned about licensing of both code and 'art' assets.
http://patware.FreeShell.org/game.htm is my own (messy) list. AGNUcius 20:22, 16 May 2012 (EDT)
http://HappyPenguin.org is another news site, but arbitrarily mixes proprietary with Free, so should not be linked directly.
