-I am a petite woman, dark skinned, dark haired, brown eyed. I have a distinct personal style, and only certain designers resonate with it (Context).
-I want my personal SAKS Fifth Avenue which carries clothes by those designers, in my size (Commerce).
-I want my personal Vogue, which covers articles about that Style, those Designers, and other emerging ones like them (Content).
-I want to exchange notes with others of my size-shape-style-psychographic and discover what else looks good. I also want the recommendation system tell me what they're buying (Community).
-There's also some basic principles of what looks good based on skin tone, body shape, hair color, eye color … I want the search engine to be able to filter and match based on an algorithm that builds in this knowledge base (Personalization, Vertical Search).
Now, imagine the same for a short, fat man, who doesn't really have a sense of what to wear. And he doesn’t have a wife or a girl-friend. Before Web 3.0, he could go to the personal shopper at Nordstrom.
I have two reasons to want this. From a human factors point of view - it is the gold standard. It considers just what the user wants and gives it to him/her with no unwanted stuff (the target content, the whole target content, and nothing but the target content).
But also, I have found that my own personal tastes are somewhat unique - so no systems that use generic collaborative filtering or community seem to give me what I am looking for. So for my own personal use, I need some serious web 3.0 action.
