Which free software alternative is the best? Which free software alternative has better potential? (Not necessarily the same one) On the FSF website they list high-priority free software projects, but the first three I clicked in the Skype section hadn't been updated since 2011, 2010 and 2009 respectively. Finally I clicked Jitsi and saw a 2012 update. http://www.fsf.org/campaigns/priority-projects/ http://www.fsf.org/campaigns/priority-projects/ I have pretty much one chance to move friends and family off Skype, so when/which alternative will it be?
