I find myself clicking ads on only two sites: Reddit and Facebook (among the 20 or so sites I don't adblock). Facebook has been pretty good at personalizing ads towards me (although I had to hide the ads that went along the lines of "learn to code at so-so online uni"), but what gets me to click is the "This many friends liked this". Digital word-of-mouth really is effective. Maybe I'm some extraordinary exception... I would still think Facebook has an amazing potential make a profit. I mean, it sure helps that it has 900 million customers/products.
