I’ve never been a big fan of the online personality tests (e.g. “What kind of tractor/hairdo/sandwich are you?” but they are clearly a fad that won’t go away. And the other day I finally heard a compelling argument explaining why so many of them exist: many of those tests are created to build personality profiles about you and people like you. That stuff feeds into how advertisers target your demographic or even how politicians speak to you. Creepy, right?
There’s no free lunch. If you can’t figure out how a website is making money, you are probably the product.
