This is really not my experience. My facebook ads are so relevant that they almost seem like a useful service at times. It knows a few of the things I'm interested in thanks to who I'm friends with or pages i've liked or whatever - so I see ads for RC planes, chess software, local restaurants... the ads seem both more relevant and less spammy than my google ads.
This is interesting. I only "liked" friend posts or pictures. May if I "like" more direct things like restaurants, brands, facebook may be able to provide me a better "ad" experience. But, its good to know that it works for some people.
