Here's an interesting study that looks at how introverts and extroverts use social media. The study looks at what words are said the most by both sides, presented in typography below. Introverts first, extroverts second...
I'm going to be completely honest here. The introverts cloud of words looks a lot more interesting to me than the extroverts! You have Pokemon, anime, manga, computers, zombies, drawing, final fantasy and more. The extroverts have a lot of vapid phrases in there like chill, chillin, babe, text me and more. I'm not knocking either side or the interests of either, but if I had to choose, I'd go with the top cloud! Thanks to 8-Bit for the heads up!
