Most of the time when I look through my Facebook newsfeed I'm glad to catch up on my friends and what they're doing, hawking, sharing, etc. Sometimes, though, someone posts stuff and makes me realize that I don't actually know who they are and really don't want them showing up on my newsfeed. Yeah, I know I can actually "mute" them or set it to only show their most important updates, but what if I just want to unfriend them on Facebook?
