Based on all the anecdotes floating around, this one included, I wonder if part of the problem is that the demographic groups advertisers (that use Facebook) really seem to want to target are the most resistant to the ads. This would then lead advertisers to broaden their targeting to the point where Facebook's enormous trove of data is basically useless. Who cares if your ad is being shown to the exact 50,000 people on Facebook who are a perfect fit for your product if nearly all of them refuse to click on it? So you broaden your demographic selections, the ad goes out to 500,000 people now, but now your product has no relevance for the vast majority of the people seeing it. Not sure, just thinking "out loud".
