The people on the bottom step are the ones who haven't realised that the stone is already rolling and that the world is moving on. These folks are still working with the temporary solutions that are LMSs and ITS systems (temporary in that there existence is only justified in the narrow technology deficit decade of 1995-2005 - where IT skills were playing catch up).
The people on the first step, and I like to think that this is where I live, are focused more on the reality of students today, they are excited about social software and radical new ideas like Second Life (radical in the non-fictitious sense anyway!). They enthuse about the wisdom of crowds, loosely coupled systems and mashups. But even these people aren't really in the right place, because this stuff is happening anyway - there are teachers out there using second life, lecturers building learning communities on Wikis, students sharing their experiences on the blogosphere. The people on the first step don't have to enthuse, this is the reality.
So what's the second step, what should a conference like ICALT be serving up on its east-west plate? I think that we all need to move forward to a place where we can set the enthusiasm aside and begin to think more critically about social software and the consequences of all this can-do power in the hands of our students. At the minute we're so busy trying to persuade everyone that the rolling stone is right that we can't take the time to reflect on the times when it rolls down an inconvenient gully, or crushes a pedagogy when no-ones looking. How do we deal with the sidelining of experts, how can assessment cope with so much sharing, how can we manage cultural differences that might disadvantage some students in online settings?
As we left Japan I realised that despite Marc's excellent talk, this is what made me so dissatisfied with ICALT this year. No-one seems to be asking these difficult questions - and surely that's what the academic community is for?
