I mean, I don't mind contextual ads.

I am somewhat sensitive to data mining but I guess not as much as other people on HN, given I am almost anonymized on the internet.

The worst thing about ads is security, and that's why I block ads even if I am browsing with significantly anonymous profile. Performance is a nice bonus.

I don't think data-mining based ads work well in practice. User_analyze.py can't tell whether I have already purchased the product I searched an hour ago, or lost interest in it. I have yet to see a good recommendation system based on data collection. Blame the big data / machine learning hype.
