> It means reaching people when they are in the mood for spending on your product (the right time / the right place). I know that and agree.

I have to admit that I don't have any data to back up my thought, and maybe what I'm talking about isn't what other people are talking about when they think about targeted advertising. > How about a woman that has uploaded photos of her newborn to Facebook? Isn't she even more likely to be willing to spend money on baby gear if she's just spent money to put them up on a paid photo sharing site (Flickr Pro, or whatever)? Like I said above, that's my untested hypothesis.
