This article does not have to do with Cyber Security, but shares an interesting point how Facebook has a good idea of who each and every one of us are, based on how we react to certain things. Last year, Facebook introduced reactions to posts, which differed from simply just liking a post. Many users in the past argued for a dislike button, but instead Facebook released reactions. Now you can love something, like it, be shocked, angry, etc. Facebook gathers information about how we react to posts containing certain words, and will show information we like or love in our feeds more often than posts containing key-words that we were angry about.
