I toyed around for awhile with an idea I called Gadfly. Basically it's an idea for complete opt in advertising. It would have a dashboard for setting up what ads I want to see. So I could put in friends birthdays, things they like, and around that time get relevant ads of things to buy that they may like. Or I could say that I need a new laptop, and while I browse see relevant ads for what I want. I was hoping to make ads work for me, as I do understand 1 big reason for marketing, letting me know things that I want are available.
