I left early, I liked the part about the maps and the guy there was funny for 7:15 AM. I think they hired an actor/comedian and gave him a script or else he has a side job at corporate parties.
Professional Learning Networks in Second Life:

You may recall my wicked kung fu from January. TIES' Second Life space is growing, we have a more permanent building but we just don't know how to develop the community we are looking for. This session is from a group of educators that created DEN, the Discovery Educator Network. It's exactly what it sounds like, a network of teachers in SL collaborating.
What I like: people doing what we are hoping to accomplish in SL. There are people behind me that are a part of Lighthouse Learing Island (Kathy Schrock's area). I want to talk more with them.
What I didn't: Not much on the how. I want to know more about how they are doing professional development. I agree with what they said, you need a little time to play, to learn how to operate in SL, but what I wanted was to know more about a formal structure of how they are meeting in SL. Meeting times, locations, how to set up a classroom or meeting space?
