I have read a bit about both connectivism & rhizomatic learning, and I, too, am interested in figuring out similarities and differences. I went through what I think of as a connectivist MOOC a year ago, etmooc, and I think that there definitely was a strong element of connecting between people as well as with knowledge, resources, etc. I felt that the idea of community as curriculum really fit well there. And yes, having peer support, making connections to individuals made all the difference to me there–otherwise I would have felt overwhelmed, I think! Those connections to people have lasted already a year, many of them, and I expect at least some to last much longer.
I’ve signed up for rhizo14, but so busy with regular job (I teach philosophy at a Uni) that I don’t know how active I’ll be. But I’ll try!
