I came across this video through a link on my Twitter feed (sorry have lost the link for credit). I wasn't aware that those who were invited to this event videoed and then published on the Festival website and made freely available.
A couple posted there I've heard before, like Michael Fullan for example and is always worth hearing. However this guy, Christian Long is someone I've not heard before, not that that is criteria for giving someone your attention. However based on the Twitter referral, I started the video. Christian has an engaging style and depth of thinking that you find yourself wanting to watch and learn.
Well worth the 56 minutes and 23 seconds.
