"Why I Lost My Faith In Facebook Advertising"

Interesting argument that advertising on Facebook is substantially different from advertising on Google.

People go to Facebook to interact with their friends. It is fundamentally different from the ad platform that is Google. People go to Google to find something they need, possibly ready to buy, which a good percentage of the time can in fact be solved by someone’s ad. Facebook ads, on the other hand, annoy users. They yield no real value, and thus no profits.
