Here's one I think would be loved by Madison Ave, but I would love it too. I would be happy if advertising was actually targeted to me and my preferences. I just don't want the people knowing who I actually am. I want them to know I'm not interested in Gap clothes, but I am interested in American Apparel. I want them to know I am not 17, but not 45. I want them to know I like Honey Nut Cheerios, but not the plain version.
Heck, I'm even advocating that I'd go for a specific advertising web page, made for me to browse stuff that I want or could want. Like Amazons' "If you like X, try Y" idea, but for everyone to join in. MyPersonalShoppingMall. I want it to learn, like StumbleUpon, what I like and don't like. Maybe I even want to meet people who have bought an iMac, or who like Ben and Jerry's Ice Cream. My identity would have to remain anonymous for sure, with a specific email addy just for shopping in my personal Web Mall, with a new low-interest credit card that rewards me and the vendor for getting my needs met. Hell, Yes. Show me the creme de la creme of new environmentally friendly LED lamps, then point me to the right low-VOC paint you think I might like, then link me to three people in Seattle who bought both of those things so we can meet up and go for a rollerblade to Marymoor Park.
MMMMM, perhaps if I did sign up for the service of targeted ads, I could tell my browser to opt out of the ads that target me so randomly and ineffectively in my normal web experience. That's the thing, I don't mind ads, just ads that suck and have nothing to do with me. This is an idea that's X2, and I don't mean maybe, baby.
