Permission Interfaces for better dialogs

We loose our innocence every passing day..we call it learning the ways of the world...
so is designer goes through this maturity curve, he learns the ways of the world; undones all the notions when he was fresh out of design school. We used to have these rosy ideas about appropriate design... we still do but in more pragmatic frame of mind.
I was under the the deep influence of design bible "design for the real world"by victor papanek. I used to look at the marketing efforts and their right hand mercenaries for all the dirty work - the advertisers, in utter disdain. I still think its a bad use of creativity.
As papanek opens his book with a line - "advertising is world's phoniest profession which tries to influence people to buy things they don't need with the money they don't have and to impress the people who don''t care."
And now here I am reading this book "Permission Marketing". It teaches you how to bait a stranger to be a friend, and then a customer.. of course I am not out there to sell anything. My whole focus is this books emphasis to use of the web for 1:1 with masses as against traditional interruption marketing techniques of the conventional mass media.
But it is good to learn from things you feel unethical and immoral, right? so When sachin says he wont endorse cigarettes one feels good about him..
neways...in this book Seth Godin succinctly take you on to changing nature of marketing efforts with time and media...what amazon did to web and how its changing the ways businesses are done.No, its not going to be another dotcom dud. Web is mature now if it is not already said enough. Core values and mores of the permission marketing is so very relevant to UXD since its finally the UIs that get influenced by this pitch and approach. And finally out there on web and its clutter and overload of information - you are in a selling business..may be not a commercial product or but of course an idea or a sequence to do things.. wherein step by step permission interfaces are more desirable than in your face interruptions.
