every story that holds interest follows a simple equation. Never more eloquently put than in Family Guy... (insert funny clip for once...check me)
Anyway, my somewhat tenous point is that this is only any good with hindsight. Relating this to the issues (still) facing marketeers today is impossible because i'm not convinced we know who the protagonists are, the antagonists, the twists in the tail. Jesus, we could still be at the foreward for all I know.
The point is that thinking you've finished the journey becuase you've finally stopped the mass media shotgun approach with every communication you do, just won't cut it. Figuring out there's a conversation going on that you need to be a part of is better but i'm still not convinced that's it either. Half of the job of a digital marketer is to be a subplot anyway - until the digital future is fully mapped out...which could be another few years at least yet - we're all in the dark.
Brian's book is further ahead than the one we're trying to get through in reality. So, I suppose the moral of this story is just keep the ego in check and remember there's a long bloody way to go yet. Even if you have been on a course and everything.
