The funny thing about targeted advertising is that I search for things I know nothing about, rather than things I'm interested in. So I get advertisements based on this or that which is related to something someone mentioned and I had no clue about until I googled it. The things I do have an interest in, I find information about from specific sources. Although, when it THINKS it knows what you're interested in, provides those ads as a replacement to one of the "one weird trick" ads. Oh, and as soon as we move to targeted ads on TV, expect to see one weird trick every episode, at a minimum.
