I actually think the ads on Facebook are done in a transparent and un-annoying way. Unfortunately, they only show me two things: 1. Geeky shirts with "clever" sayings on them (since they know I'm a programmer, I guess). 2. Things I've already recently bought on Amazon (or elsewhere). In the first case, what they know about me leads to a severely mistaken impression regarding something else about me. In the second case, what they know about me is already outdated.
