ISPs might do well at profiling the interests of some of their customers. But for people like web designers, writers or journalists, an average day might see them browsing an eclectic mix of sites on everything under the sun. And what if you've got a couple of people like that, or a bored teenager or two in the household as well? I wonder how useful this information might be to an advertiser?
So I just had a thought: rather than assiduously trying to cover our steps by using VPNs, Tor, Https Everywhere, Privacy Badger, or whatever, maybe an opposite strategy would be far superior.
A call to app or browser extension designers: give us something that can randomize browsing history. Automate sending our browser on a day-long crawl across multiple and sundry websites. The resulting web history would be pure gibberish, of no value to anyone. Furthermore, it would quickly become obvious what was happening: our browsing history would become just as worthless to the government surveillance agencies that are tracking us too.
