I just pick now Marsha Coilier, she is a strategist, but there are other manners to build nice commerce portals take a little bit job but i guess it works. First step are community portals now with the "search boxes API's", simple in fact, can use blogs and create dozens of them. You don't need to buy anything that you can have someone delivering to you with a small fee at 1mile distant, you just don't know where is it, and everybody in world have such problems.
You go to WEB to look something that first you don't look, where is closest, you go to WEB them enter on a mega dispute, trying to save 2-3 dolars. Typical from compulsive gamblers, that is why are 2 different things, Giant Trade Markets from Giant Use Cases from a simple well mounted "graph with local search engines". I just saw a work from a girl that did this with retail houses, nice work indeed, finishing the interface she even need more advertsing just "edwards". Adverting like "panels" flash are that which really works, besides have a nice interface attract user interest, problem is that they start to shrink when the visits increase.
So a marketing strategy really means "surround the fooler" on graph networks, and don't give him peace, to do this, persons need to understand what they are seeing in the announces, it seems that 80% of the population aren't understanding visual messages. Because came from the culture of the broacast where everything is thrown on his face, there is no effort to look for nothing more.
The correct word if i am not wrong is mitigate the user until he learn what are subliminal messages and they exist not for "his bad", is just a perspecitive of visual interpretation, and there is nothing to do like the "technoratti claim" with brain redux, it is completely oposite, is social hacking analysis.
