Very true. Customer data is big business, yet year after year it fails to deliver. Another classic is the repeated ads for the dish washer I just bought, for months at a time. There are glimpses of potential with targeted search results. It can be practical, for example when I search for open source software named after a common word. So the technology is there, but isn't remotely used to its potential. My only guess is that there is only so many advertisements available in the pipeline at any given moment. It's the 90/10 rule all over again.
