The answer isn't actually quite shocking. According to a new study from NM Incite, a company owned by research firm Nielsen McKinsey, actually knowing someone in offline (real life) is the No. 1 reason users add someone to their friends list. Posting "offensive comments" is the primary factor in people hitting "delete." Surprised?
Here are a few more, perhaps more interesting, tidbits: The average Facebook user has 130 friends. Men use Facebook primarily for networking, and dating, while women use social media "for a creative outlet, for coupon/promos and to give positive feedback," all of which sound incredibly stereotypical — possibly even sexist. Connecting with family and friends is a big reason for using the social network, as is networking and other career-related activities, and entertainment. These are of course, very obvious.
