Kind of hard to follow - Steven Downes describing his white board scribblings in a noisy room. I like it because it is authentic. I've listened to it more carefully now prompted by your posting. I like networks much better!-
thanks-
I've noticed that Stephen Downes isn't the best user of media but what he says always intriques me. His description is exactly why I prefer networks to groups as well.
