So much this. I would turn my adblock off, if I had a directory with checkboxes/weights against interesting product topics. I would even browse the topics themselves regularly, as I did in google directory before it was gone. I (and the economy) want me to discover, not to hide from pushiest pushers around.

Modern marketing is just a slowpoke idiot who stalks me for two weeks after I already bought a <productname> via search.

Google’s system isn’t perfect but I can x-out individual ads. I’m hoping that Google will move away from a purely embedding-based targeting system into something more deliberate.

Facebook has [1] which is the closest to what you are asking for, although not used nearly enough to justify more investment in improving it.
