Twitter has just announced a new mute feature thatll let you shut up the annoying people in your feed, at least temporarily. If, say, one of your friends is at a conference and is just babbling non-stop about the parties hes attending, you can now mute him. This removes his tweets and retweets from your timeline without you having to unfollow him altogether — think of it as a kinder and gentler blocking, if you will.
