Just a quick blurb here- I found out this very evening about a group of young people who are attempting to create a social network that is open source and concerned about privacy issues. Evidently this will all happen thru the use of nodes which the individual consumers own ie, if you join this project *you* and you alone will actually own and control your very own node in the system. No more relinquishing control of your privacy and identity over to Twitter or Facebook or whomever or joining networking site you don’t give a rip about. If you want to find out about your friend Joe you will no longer need to join everything that Joe is a member of you can simply have your node talk to Joe’s node and find out what you Joe has been saying.
This is all still VERY early in developement but they are shooting for a release by the end of the summer. Give it all a read through at http://joindiaspora.com I anxiously wait to see what they come up with and how it will work.
