A social media account where people can share mini blurbs of 160 characters or less "Favorite" means that the reader deems the tweet interesting or entertaining while a "retweet" means that the reader deems the tweet interesting or entertaining enough that they want to share it with their own followers @OUCrushes "I am kind of developing a crush on the notoriously slow swiping brunette girl at Shively" @OU_Confessions "I wear the Voice shirt around campus to make my friends happy, but I am secretly voting for Fuss" Extra whipped cream to go please RT @MaryDeRoy: @bobcatmakeOUts they are having a sonic blast pic.twitter.com/Tc29pyojJC @BobcatMakeOUts We collected data by getting together and counting both favorites and retweets of 22 tweets from each account before 11:59pm on April 6th What We Controlled How long each tweet has been exposed
