This is a valuable thread to pull thank you: how about differentiating targeted, sticky advertising vs context based advertising. On my local paper website, I value being shown local stuff (to your point on small business). On security websites, show me security products. On HN, Show me tech and science.

The ADD incidence rate being 10x for adults since 2005 (not to even mention kids), we'd all appreciate relevance to what we're exploring/thinking about/learning, rather than the genuine nuisance of nagging for something out of context because we're tracked all around the web.
