Personal Learning Networks

Today I attended a webinar on Personal Learning Networks - how do I stay connected to others who are interested in the same things that I am. My PLN consists of several listservs that I'm a member of - CFF Coaches and LM_Net, my staff and tech people at school, and a few others that I talk or Skype with. I have found that there is SOOO much more that I could be doing. Some ideas: facebook, Nings, Diigo, Twitter, LinkedIn, Keystone Commons and Synmbaloo, just to name a few. My next step is to check out all of these items and see what is going to work best for me. I hope that I am part of my staff's personal learning network through our Moodle and Wiki - I'm planning on adding a page about personal learning networks on the new Google site - hopefully my pln will grow :)
