> That's the kind of change that turns an unviable business into a viable one. What, like going from 1 in every billion people clicking on your ad to 1 in every 100 million? I'm sure that in some niches there is going to be a particular data set that yields mega results for someone. But I'm talking as a general concept, that the whole advertising industry is built on total lies all the way down and that all the data mining hardly moves the needle compared to context-related ads like my example. I suspect that no one wants to know if it actually works or not. It'd be like pulling on a thread that everyone can see, plain as day, but no one wants to touch it as there are hundreds of billions of dollars on the line if they do. That, plus people are employed and have livelihoods built around ads so they won't jeapordise that. I don't buy it. I still think it's all bullshit. But let's say it's true. There still remains the fact that many don't want their data in anyone's database in the first place. It's an industry built on gathering data without consent - and before you say there are opt-outs and all that, the industry built itself up long before any rules came into effect.
