Another PD video I watched was 7 Degrees of Connectedness by Rod Lucia. I really enjoyed this presentation. Rod talked about using different tools to connect and that one needs to take risks, start small, but the relationships you create will become invaluable. He touched on a few different tools, but mentioned that voice itself, is very important. It adds a more authentic connection to the tweet, blog, podcast, whatever you do.
I recommend connecting on the K12 Online Conference site for some invaluable PD in your pj's!
