This study really makes me feel vindicated for unfollowing all of my friends along with every brand on facebook. I could've been part of the study but I'd never know, since the only way I see my friends' posts is to visit their pages directly where I can see them all unfiltered. I've been doing this for the past six months and it has dramatically improved the way I interact with the site. I can still get party invites and keep in touch with people, but I'm immune to the groupthink.
