Because I'm a passionate advocate for Free and Open Source Software in K-12, I've been feeling for a while that the time is right for a stand-alone social network around its use. There is a good K-12 Open Source group within the Classroom 2.0 community, but groups don't have the same full functionality as stand-alone networks, and also don't have the same visibility. So I've done some reconfiguring with my www.K12OpenSource.com domain, creating a collaborative site which I hope will help to build the Free and Open Source Software ecosystem in K-12. The wiki that was previously there is now at http://wiki.k12opensource.com/, and I've set up a Ning community just for Open Source in K-12 at http://community.K12OpenSource.com/.
I hope you'll come join the community and help to build it. I believe that having an inviting and easy-to-use social network will increase exposure, adoption, and idea-sharing around Open Source in K-12 at a time when it is truly needed (both financially and pedagogically). We'll also need some folks to start groups around favored programs--please consider coming and doing that!
