Looking at my data, it's so so so tempting to opt-out, but then again I'd rather see targeted ads than 'one crazy trick to get rid of my belly fat' ones....
Say what you will about the creepyness of automatic profiling, but in my experience it has made some significant progress towards advancing advertising from a necessary evil to a genuine value-add.
Is that actually the kind of ads you see? I've been using AdBlock since forever, but I assumed all the ads were flashy commercials for everyone. Maybe my friends without AdBlock are just boring.
This is clearly not the same data I had when I used their web service at a startup I worked at in 2000. They had a service you could provide a phone number to and it would return a little story like this:
"Bob Smith from Portland, Oregon uses in-home pregnancy tests, drinks imported beer, and listens to alternative rock radio stations."
None of those sorts of rich details are in my data.
