Money I guess. I'd be interested in seeing a blog post analyzing how all this stuff gets used. For instance looking at https://www.theguardian.com/uk https://www.theguardian.com/uk I can see hundreds of cookies against their site and loads of associated advertisers. Most of the items are a load of hashes and ids etc so how does all this stuff get used in reality and what are they actually storing - is it just a journey of clicks on that page etc?
