I attended Seth Godin's presentation on his new book, Tribes, last week. In addition to being a superbly organised event at a great location in New York, Seth came across as a person who is every bit as passionate about his subject matter on (and off) the stage as he is on his blog.

Seth’s new book is all about leading groups of people, whether that be in a commercial marketing context (his home territory) or in the wider realm of organisational change, charitable concerns or passionate causes (such as expeditions).

The three hour non-stop event (which included more than an hour of Q & A) provided me with 12 pages of useful notes to implement.

One of the biggest revelations for me was Seth's concept that as a leader of a group, you get to lay down the strategy, but the individual members decide the tactics. By sharing this insight, Seth provided me with the missing piece of a puzzle to a project I've been mulling over for some time.

The slides that Seth used in his talk can be viewed online, and I've uploaded the audio if you want to hear what you missed. (I edited out the live performance by the talented Jen Chapin who played for us mid-way through Seth’s presentation.) The Tribes book is available on audio too, for just a dollar through iTunes. A bargain.
