When apps like Facebook first debuted, they didn’t allow users to “like” other posts or tag users. It’s not a stretch to say the like button was one of the best innovations of the last decade, but perhaps also the worst at the same time. Tagging and liking on social media were not part of the original business model. These “approval indicators” as they are known were invented after the fact. In fact, you might be surprised to learn that the “like” button was not added to Facebook until 2007, three years after the social network launched. Why d you think you are hooked on social platforms ?
