I attended Steve's CGW2. I found Steve's presentation good. I believe Steve provided some important value to the group. He provided this value by being:
The commonality that attracted participants who were interested in change.
Providing the location and other logistics for the workshop.
Explain his framework of understanding.
Encouraging people to spend time with fellow attendees.
I believe many participants received value from their attendance. I liked hanging out with others at the conference and discussing where we were and where we wanted to be. I think this bonding with real people is at least as important as the material presented in this and most other workshops.
I know of some participants who benefited from the weekend rather dramatically. For them the change seems to have been sticky and not temporary.
I've been to other events as participant. The workshop was better than many I have attended. There are many less healthy and productive ways to spend a long weekend.
I didn't expect Steve to be perfect or the ultimate guru. I did not view him as a guru. I've worked with celebrities before and know they are human as am I. In my opinion Steve was good as a presenter. As with all people offering a perspective I embraced the part which I believe to be useful to me and discarded the rest.
I would attend another of his workshops. I had fun with the event, the presenters and especially with the people attending. YMMV
I had fun at the event and just for the entertainment and fun the price of admission was reason able.
