"My interests" are hard to define without collecting far too much information about me. Good example for "of interest" in my opinion: If I shop with Amazon and bought Product A, B and C and your database of previous orders suggests that I'd like to buy the new Album of Justin Bieber: Fine, go ahead and suggest that to me. In that case you used just the information that I sent to you and correlated that with a little bit of inventory/anonymous order history magic. I get recommendations from you because I am your customer already and provided you with a limited insight into "my interests". Now - if you track me across sites, try to create a profile of me without my consent and my explicit knowledge and then try to sell this as being relevant, a good idea and targeting "my interests" I have some doubts that we're talking about the same thing.
