Currently a LinkedIn group to develop the structure, the idea is to continue a sequence of conferences from about ten years ago. My own take is that the first MTW went a bit off course with the closing keynote from Chris Grey. He persuaded the academic part of the audience that universities have a better basis in critique than in claiming to offer effective practice. So the idea of mixing academics and practitioners did not continue. There was also a turn from learning organisations to leadership which again I think was unfortunate. Of course organisations need leadership but charisma is in a context.
Critique is included in the current scope and comment is welcome. There may be a face to face event in late 2012 but the online aspect is expected to continue.

I hope they have a look at Twinity St Pauls.
